                          Introduction
                 Most DVD movies are dual layered (4.7 GB to 9.4 GB), while DVD recordable media are only
                 single layered (under 4.7 GB) - this means that sometimes you'll have to split a DVD movie
                 onto two DVD recordables (instructions on how to do this can be found here).

                 DVD Shrink is the a free software that allows you to "shrink" existing DVD movies (by
                 removing content or reducing their quality) so that they will all fit onto a single 4.7 GB DVD
                 recordable. DVD Shrink is the first software of this kind that is actually free, and has DVD
                 decryption functions built right into the software.

DVD Shrink allows you to reduce the size of the DVD in two ways. One is to remove content from the DVD
(eg. remove extra features), and the other is to keep all the original content, but reduce their quality and
hence, file size. This guide deals with both methods.

The shrinking process will reduce the quality of the movie (that's where the file size reduction comes from).
If you want to keep the original quality of the DVD, then you can use this method to split your 9.4 GB DVD
onto 2 4.7 GB DVD recordables.

While quality has been reduced, the content of the DVD (eg. subtitles, extras) can be left untouched. It is
also possible to select which part of the DVD gets "shrunk" and which remains the same (eg. shrink the
extras, but keep the movie untouched), as well as completely stripping away content (eg. only keep the
main movie).

DVD Shink 3.1 and later now comes with DVD burning capabilities (required Nero Burning ROM), which
makes DVD Shrink even more complete and the backup process even easier.

Summary of procedures :

            1. Optional : Ripping the DVD - Rip the DVD with DVD Decrypter prior to using DVD Shrink
               (Recommended);

            2. Setup DVD Shrink - Setup DVD Shrink when using it for the first time;

            3. Configuring the backup - Using DVD Shrink's Full Disk or Re-Author modes to backup the
               entire DVD, or just parts of it;

            4. Choose how to burn the backup - Choose to use DVD Shrink's built-in burner, or use
               external tools to burn the backup;

You can start using this guide/tutorial by going to the next page or clicking here.

Archived versions of this guide (for the older 1.x and 2.x versions of DVD Shrink) are also available at the
end of this guide. To proceed with this guide, select only one of these sections from the index below.


Disclaimer : While making backups of DVDs that you already own for personal use is perfectly legal (as it
falls under fair use), it is illegal if you make backups for commercial gain (such as selling your backups, or
selling/returning your original after making a backup). This guide is present for educational purposes only,
and does not condone any form of piracy.



                  Using an External Decrypter
The following instructions are for using DVD Shrink with an external DVD ripper, specifically with DVD
Decrypter. Doing this requires more hard-disk space, but will mean less constant DVD-ROM access
(although to be fair, the access is no worse than playing back two DVD movies one after the other). It also
means that certain specially protected DVDs will work with this method, rather than ripping
within DVD Shrink itself (more information here). If you don't want to do this (ie. you want to use
DVD Shrink's built-in ripper, and don't mind the extra DVD-ROM usage), then go to "Step 1 : Setup DVD
Shrink" or click here to skip ahead. Otherwise, read on ...
 Requirements (for this step/page):
   14 GB of free hard-drive space (up to 8.76 GB for ripping DVD, up to an additional 4.38 GB for backup
 disc)


 Software Downloads (for this step/page):
  DVD Decrypter




i.      Insert the DVD you plan to backup. Start DVD Decrypter.

          ii.      From the "Mode" menu, select the "File" mode (or press the "F" shortcut key). This should
                   load the DVD and display all the files on the DVD in the window on the right hand side.

                   Important #1 : You need to remember which title set and files contains the main movie.
                   The main movie's title set and it's files are highlighted by DVD Decrypter upon loading
                   (sometimes not all the files in the set are highlighted, since they may not be part of the
                   movie). In the picture below, the highlighted title set is VTS_01 (although VTS_01_0.VOB is
                   not highlighted and not included in the set).




                                      Ripping in File Mode - highlighted files contains main movie




                   Now highlight all the files (we want to rip every single file on the DVD) by using the mouse,
                   or pressing the "CTRL-A" shortcut key.


                iii.        Now change the destination of the output file by clicking on the   icon.

                   Recommendation : I recommend that you rip the DVD to a folder of its own, as opposed to
                   ripping the files into a folder where files already exists.




                       Selecting the output destinatination - make sure there's enough hard-disk space, which is
                                                      not the case in this picture
             iv.         This step is optional. We can change some of the settings for DVD Decrypter to
                specify the ripping options. To do this, from the "Tools" menu, select "Settings". Then, go to
                the "File Mode" section.




                                                    Selecting the File Mode options




                   The options that are of interest are :

                   a.       Remove IFO/BUP RC Protection - removes region protection from the copied
                   DVD
                      b.    Remove IFO/BUP RCE Protection - removed RCE protection (an advanced form
                            of region protection) from the copied DVD
                       c.   Remove PUOs - some DVD movies prevent certain actions to be taken at certain
                            time (eg. you can't change the subtitles while the movie is playing, or your can't
                            skip past the copyright message). This option will remove these limitations.




              v.           Now click on the large "Decrypt" button to start the copying process. DVD Decrypter
                   will now copy all the files on your DVD to your hard-drive. You can close down DVD
                   Decrypter once it has finished ripping all the files.




                                            Start the Decryption by clicking on this button

Optional: If you want to get better quality within DVD Shrink, you can optionally use the steps in this guide
to process the ripped DVD (using VobBlanker) prior to using DVD Shrink.



                                            Step 1 : Setup DVD Shrink
In this step, we configure the DVD Shrink settings. You only need to do this for the first time you use DVD
Shrink, and so if you've already setup DVD Shrink, go to the next step (Step 2 : Configuring the backup) or
click here to skip ahead.



Software Downloads (for this step/page):
 DVD Shrink 3.x




   1. Start DVD Shrink.

   2. From the "Edit" drop down menu, select "Preferences". In the window that pops up, you can
      configure several of DVD Shrink's options :
                              DVD Shrink - Preferences - Preferences




The options explained :

   1. Target DVD Size : - this states the target size of the backup you wish to make. Normally,
      the default option of "DVD-5 (4.7GB)" is what you will need if you plan to make single disc
      backups. Note that 4.7G in DVD-R notation actually translates to 4.38GB in normal
      computer notation (eg. those that is reported in Windows Explorer) - this is because 1G is
      equal to 1,000,000,000 bytes, whereas 1GB is equal to 1073741824 bytes (1024 x 1024 x
      1024). Alternatively, you can specify your own custom size in MB.

   2. Hide audio and subpicture streams of insignificant size - on certain DVDs, there may
      be lots of audio/subpicture streams that are not important in terms of shrinking (ie. they
      can't be shrinked much). Selecting this option will make sure these insignificant streams are
      not shown, which is the recommended setting.

   3. Automatically open VIDEO_TS subfolders - when this option is selected, DVD Shrink will
      look for the "VIDEO_TS" sub-folder in your current folder and use it for backup. There's no
      harm in leaving this option selected.

   4. Run analysis and backup in low priority mode to improve multi-tasking - if you plan
      to use your computer while you are shrinking, then selecting this option will mean that DVD
      Shrink will only run when there is free CPU power. There's no harm in leaving this option
      selected (it won't make processing slower if you are not multi-tasking).

       Now go to the "Preview" tab ...




                                    DVD Shrink - Preferences - Preview




   5. Enable video and audio preview - this option should be selected, as it will help you see
      what you're backing up
6. Select audio preview mode ... - this option determines what surround mode the audio
   preview will be in

7. Select DirectX video renderer : - VMR-9 allows other video application to work while you
   are previewing video in DVD Shrink. If you don't plan on using other applications, then
   select VMR-7 or Overlay Mixer, as these modes will be faster.

   Now go to the "Output Files" tab ...




                               DVD Shrink - Preferences - Output Files




8. Remove Macrovision protection - the name says it all

9. Remove P-UOPs - selecting this option removes prohibited user operations (eg. copyright
   screens that you can't skip past, or not being able to change the audio track while playing
   the movie). I would keep this option selected, as I hate being forced to watch a DVD in a
   certain way.

10. Remove layer break - dual layered DVDs have a layer break which causes a small pause in
    playback. Since we're backing up to single layered DVD±R/RWs, keep this option selected.

11. Split VOB files into 1GB size chunks - DVD compliancy requires VOB files to be less than
    1GB, so make sure you have this option selected.

12. Logical remapping of enabled streams - if you remove content from the DVD, then
    selecting this option will cause DVD Shrink to remap the content so that you don't notice the
    missing content (eg. if you remove a subtitle track, then it will no longer show up as an
    option on your DVD player's subtitle selection menu). There's no harm in leaving this option
    unchecked, as this option doesn't always work.

   Now go to the "Stream Selections" tab ...




                            DVD Shrink - Preferences - Stream Selections
       13. Audio language and coding type, Subpicture language - these options determine the
           default language/audio types DVD Shrink will backup. For example, you can set it up to only
           backup French LPCM tracks with English subtitles (if the DVD you are backing up has these
           options)

       14. Disable all subpicture ... - select this option if you don't want any subtitles, other than
           menus and forced subtitles (those that you cannot turn off normally, eg. when a character is
           speaking in a foreign language)

           Now go to the "File I/O" tab ...




                                          DVD Shrink - Preferences - File I/O




       15. Enable overlapped I/O - as the caption says, this may increase I/O performance during
           ripping

       16. Read 32KB blocks - again, this is related to DVD ripping performance

       17. Check RPC2 drive region code when opening a DVD - disabling this option may solve
           some problems with DVD drives that have hacked region-free firmware

       18. Enable burning with Nero - this option enables integration with Nero Burning ROM. Keep
           this option selected, since we can choose not to use Nero to burn the disc later on

       19. Always erase non-empty RW media without prompting - if you don't select this option
           and the disc you want to write to is not empty, then DVD Shrink will prompt you to erase
           the disc or insert another one

           Press "OK" to save your preferences ...




3. If you want to change the way DVD Shrink's toolbar looks, then from the "Edit" drop down menu,
   select "Toolbar Buttons". In the window that pops up, you can select a different toolbar :
                                           DVD Shrink - Toolbar Buttons




                                    Step 2 : Configuring the backup
In this step, we start the DVD shrinking process and decide what content on the DVD we should backup, and
the final quality of the backed up copy.




   1. If you used an external DVD ripper, then click on the "Open Files" button and load in your ripped
      files. Otherwise, click on the "Open Disk" button - this should bring up a new window. From the drop
      down menu, select the drive which contains your DVD movie.




                                              DVD Shrink - Open Disk




   2. DVD Shrink will now scan through your DVD and work out how much compression can be achieved.
      It only needs to do this once per DVD (and it will remember analysis data, so that the next time you
      backup the same DVD, you won't need to go through the long analysis process again). The initial
      analysis is just a quick analysis, and it is not to be confused with the Deep Analysis performed at a
      later stage.




                                            DVD Shrink - Analysing DVD
   3. By default, DVD Shrink should select the "Full Disk" mode for you, which will keep all the content on
      the DVD, but will shrink the contents so that it will fit onto a single DVD recordable. The other
      option, "Re-author", allows you to remove content from the DVD (eg. keep only the main movie). It
      is here that you'll have to decide which mode you want:

I want to backup the entire DVD
I only want to backup part of the DVD




                                  I want to backup the entire DVD

                    1. Make sure you press the "Full Disk" button to select this mode.




                                             DVD Shrink - Full Disk



      2. DVD Shrink should now display 3 different panels. The top left panel is the Content Tree
       panel, which shows the contents of the DVD in a tree structure. The panel just below that is the
         preview panel, which you can use to playback the currently selected content (in the Content
        Tree panel). The large panel to the right is the Compression Settings panel, which allows you
                   to adjust the compression settings of the currently highlighted content.




                                               DVD Shrink - Views



    3. Let's take a close look at the Content Tree. This panel shows the structure of your DVD. Each
         DVD has three main components : Menus, Main Movie and Extras (and also sometimes
       Unreferenced Material, for things that DVD Shrink can't classify). Each component can have
        many titles (eg. Extras : trailers, TV spots, documentaries ... are all separate titles). The file
        size, both before and after shrinking/compression, is also shown, as is the duration.




                                     DVD Shrink - Content Tree



  To specify a single compression level for the entire DVD, click and highlight the "DVD" item.
      Otherwise, you can click and highlight any particular component or title to change it's
                       compression level individually, which brings us to ...

4. ... the "Compression Settings" panel. This panel shows the various streams (eg. video, audio,
   subtitles) of the currently selected DVD, component or title, as well as the compression level
                      you define for the currently selected DVD/component/title.




                                DVD Shrink - Compression Settings



   By default, the "Automatic" setting is selected, which lets DVD Shrink automatically find the
        highest "compression percentage" (shown just below the options drop down box - the
   screenshot above has a compression percentage of 64.3%) for the given amount of available
  space for the backup. The compression percentage is the size of the shrunk file as a percentage
    of the original size, but you can also think of this percentage is the percentage of quality the
      backup will have compared to the original (although a file that if 50% of the size of the
   original, will usually not be as bad as having only half the quality of the original). The other
   options are "No Compression", "Custom Ratio" which lets you select a custom compression
  percentage using the slider bar and "Still Pictures", which is the highest compression level you
                        can get (but the movie will now resemble a slideshow).
  Note that with the custom ratio, the lowest compression percentage you can select may differ
  from title to title, and this is because some titles can be compressed more so than the others -
  the analysis that DVD Shrink did at the beginning determines how much you can compress a
                                             particular title.




                                 DVD Shrink - Compression Options



 Our goal now is to select the highest possible compression percentage that will bring our DVD
 under the selected target size. We would also need to ensure the picture quality is not too poor,
          and preferably, that the main movie will be higher in quality than the extras.

5. You may have noticed the green (or perhaps partly red, or grey) bar just below the toolbar.
  This bar shows the current size of the backup. The green part shows what will fit within your
   target size, while the red part obviously shows how much is over the target size and the grey
     part shows part of the target size that remains unused. As you can see from the screenshot
  below, our backup is 5371 MB in size, while our target size is only 4.38 GB. So basically, our
      goal is to shrink our 5371 MB DVD to under 4464 MB, and therefore, ensure this bar is
                                           completely green.



                                        DVD Shrink - Size Bar



  Already mentioned above, one way to achieve this is to adjust the compression percentage in
  the Compression Settings panel. Another way is to user the Compression Settings section to
 deselect any unwanted streams (eg. removing the "Director's Commentary" track, which could
                                save some 200 MB in space).

 The combination of removing streams and compression percentage settings is what determines
 the quality and final size of your back. It is this combination that is crucial, and yet, this is the
               part that I can't really help you with, since each DVD is different.

  A tip is to make use of the preview panel, and right click on the panel to select different audio
      options (as well as a full screen mode) to see what you can remove and what you can't.




                                   DVD Shrink - Preview Options



  As an example, this is what I have done with the Pirates of the Caribbean (Region 1) DVD to
                                    shrink it under 4.38GB :
      o Menus : Custom - set to lowest compression percentage (compression percetage 48.8)
      o Main Movie : - kept only the first sound track, kept captions, Automatic (compression
                                           percentage 70.2)
      o Extras : Custom - set to lowest compression percentage (compression percetage 59.9)




                                   DVD Shrink - Shrunked Sizes



   Once the graphical size bar at the top turn completely green, it means that we are within our
                 target size, and that we can successfully burn a backup DVD.

    6. You can now skip ahead to the next step (Step 3 : Choose how to burn the backup)




                        I only want to backup part of the DVD

              1. Click on the "Re-author" button to select the Re-Author mode.




                                     DVD Shrink - Re-Author



2. What we are trying to do here is to create a new DVD, and then bit by bit add what we want
   from the DVD we want to backup to the new DVD. The left hand side of DVD Shrink shows
      the new DVD we will be creating and also the preview panel. The right hand side (DVD
            Browser tab) shows the content of the original DVD that we want to backup.

3. Let's take a close look at the DVD Browser. Here, you can navigate the contents of the DVD
  just like you would normally do in Windows Explorer. Double clicking on a "folder" will open
         up its contents, and you can use the "Back" button to go up to a higher "directory".
                                      DVD Shrink - DVD Browser



    A DVD is divided into three components, the Menu, the Main Movie and the Extras. By re-
      authoring, we can decide which parts of the DVD gets backed up. The most common
                  application of this function is to backup only the main movie.

4. Double click on the "Main Movie" component/folder, and DVD Shrink should now show you
   all the titles available in the current folder. Each component can have many titles (eg. Extras :
    trailers, TV spots, documentaries ... are all separate titles), or in the case of the main movie,
                                            usually just one title.




                                   DVD Shrink - Main Movie - Titles



  5. To backup the main movie, drag the titles in the Main Movie folder to the left side of the
                 screen. Repeat for any other content you also wish to backup.




                                     DVD Shrink - Drag Over Titles



 6. Let's take a closer look at the left side of DVD Shrink, or what I have dubbed the "Content
                                    Tree" and the "Preview Panel".




                                      DVD Shrink - Content Tree



    The screenshot above shows that the new DVD we want to author has only one title currently
     (the main movie title we dragged over in the previous step). I have also renamed the newly
                        authored DVD to "Pirates of the Carribean - Movie".

   You can right click on any particular title and select the default Audio and Subpicture streams
   that will be used when playing back this title. The screenshot below shows that I have selected
                      the English - Normal Caption to be displayed by default.




                                    DVD Shrink - Default Streams



     Just below the Content Tree is the Preview Panel. You can right click on the panel to select
    different audio options (as well as a full screen mode) to see what you can remove and what
    you can't, and this is very useful to find out exactly what you are backing up, as well as what
                                audio/subtitle streams you want to keep.




                                    DVD Shrink - Preview Options



7. Now select one of the titles in the Content Tree, and then click on the "Compression Settings"
   tab on the right hand side. This panel shows the various streams (eg. video, audio, subtitles) of
     the currently selected content, as well as the compression level you define for the currently
                                    selected DVD/component/title.




                                 DVD Shrink - Compression Settings
    By default, the "Automatic" setting is selected, which lets DVD Shrink automatically find the
        highest "compression percentage" (shown just below the options drop down box - the
    screenshot above has a compression percentage of 64.3%) for given the amount of available
   space for the backup - this is the size of the shrunk file as a percentage of the original size, but
        you can also think of this percentage is the percentage of quality the backup will have
      compared to the original (although a file that if 50% of the size of the original, will have a
     better quality than 50% of the original). The other options are "No Compression", "Custom
    Ratio" which lets you select a custom compression percentage using the slider bar and "Still
   Pictures", which is the highest compression level you can get (but the movie will now resemble
                                               a slideshow).

    Note that with the custom ratio, the lowest compression percentage you can select may differ
    from title to title, and this is because some titles can be compressed more so than the others -
    the analysis that DVD Shrink did at the beginning determines how much you can compress a
                                               particular title.




                                  DVD Shrink - Compression Options



   Our goal now is to select a compression level that will bring our DVD under the selected target
   size. We would also need to ensure the picture quality is not too poor, and preferably, that the
                    main movie will be higher in quality than the extras (if any).

 8. You may have noticed the green (or perhaps partly red, or grey) bar just below the toolbar.
   This bar shows the current size of the backup. The green part shows what will fit within your
    target size, while the red part obviously shows how much is over the target size and the grey
      part shows part of the target size that remains unused. As you can see from the screenshot
   below, our backup is 5371 MB in size, while our target size is only 4.38 GB. So basically, our
                        goal is to shrink our 5371 MB DVD to under 4464 MB.



                                         DVD Shrink - Size Bar



    Already mentioned above, one way to achieve this is to adjust the compression percentage in
       the Compression Settings panel. Another way is to deselect any unwanted streams (eg.
      removing the "Director's Commentary" track, which could save some 200 MB in space).

9. Another way we can reduce the size further is by editing out content from the titles in our new
    DVD. To do this, select a title in the Content Tree and click on the "Set Start/End Frames"
                                               button.



                                   DVD Shrink - Set Start/End Frames



    A new window should open with two distinct sections - one for selecting the start frame, and
         the other for selecting the end frame. For example, if you wanted to cut out the credits, then
         leave the "Start Frame" section alone, and adjust the "End Frame" section to cut out the end
         credits. You can use the slider bar to do this, or use the chapter selection drop down menu to
        select the last chapter you want to include. For this particular DVD, the credits start at Chapter
          16, so I have selected the End Frame to be at the end of Chapter 15 (see screenshot below).




                                        DVD Shrink - Set Start/End Frames



      10. Now repeat the above for all the titles you wish to copy. As an example, this is what I have
        done with the Pirates of the Caribbean (Region 1) DVD to shrink it under 4.38GB and to keep
                                    only the main movie and some trailers :

                                       o Menus : - did not include any
            o   Main Movie : - kept only the first sound track, kept captions, Automatic (compression
                                                    percentage 80.2)
                o Extras : - copied over title 39 (trailers), set compression to lowest (compression
                                                    percentage 64.8)



     11. Once you have finished authoring your new DVD, you can now go to the next step (Step 3 :
                                     Choose how to burn the backup)



                                 Step 3 : Choose how to burn the backup
In this step, we will now burn the backup.



Requirements (for this step/page):
 A blank DVD


Software Downloads (for this step/page):
  ImgTool Classic and DVD Decrypter 3.1.7.0 or better
or
  Nero Burning ROM (Demo version is fine)




   1. Now click on the "Backup!" button and you should be presented with a couple of more options.




                                                DVD Shrink - Backup




       If the current predicted size of the shrunk DVD is larger than your target size, then you may
       encounter the following screen first:




                                      DVD Shrink - Target DVD Size Exceeded




       Even if you exceed the target size, DVD Shrink can still let you backup this DVD (by selecting "Yes"
       on this screen), but you risk not being able to fit your backup onto a single blank DVD.

   2. If you have Nero 5 or later installed (the demo version will work), then you will have three options
      in the "Burn with Nero to the following device" drop down menu:
           o Burn With Nero - Burn the movie straight to a blank DVD by selecting your DVD burner
              device;
           o Create ISO Image File - create a ISO disc image file that can be burned later (with Nero
              Burning ROM or other DVD burning software) or create the image and burn with DVD
              Decrpyter straight away;
           o Hard Disk Folder - copy the backup to a folder on your hard-drive
                                           DVD Shrink - Backup Target




    Only the first option will require a working version of Nero Burning ROM (the demo will do) to be
    installed - this option is recommended if you have Nero Burning ROM installed. The second option
    comes with two sub-options, one that just creates the image, and another that burns the image to
    disc using DVD Decrypter. If the first option doesn't work for you (eg. if you get a burning error),
    then try the second option. Only use the third option (Hard Disk Folder) if you are used to using
    ImgTool + DVD Decrypter.

    If you don't have Nero installed, then you'll see a similar screen, but with the first option missing.

    If you select the Hard Disk Folder option or if Nero is not installed, you will also get an additional
    option called "Create VIDEO_TS and AUDIO_TS subfolders". Ensure this option is selected at all
    times, as otherwise, the output may not be all that useful.

    For all three options, you need to select a directory to store the output (or temporary files).

3. Now click on the "DVD Region" tab. Here, you can ensure the backup is region-free, or set to a
   particular region.




                                            DVD Shrink - DVD Region




4. Now click on the "Quality Settings" tab. Selecting either options below will mean more encoding
   time, but better quality. These options are no substitute for using less compression, so it's always
   best to ensure compression is set as low as possible.
                                     DVD Shrink - Backup Quality Settings




   The options that you can select are:

       o   Perform deep analysis ... - selecting this options will double the backup time, but will
           improve quality. You could also have selected this function by pressing the appropriate
           button on the toolbar, and if you did it before, this option will not be available. This option
           will also be unavailable if you chose no compression as the backup setting.

       o   Compress video with high quality adaptive error compensation - this is a new option
           introduced in DVD Shrink 3.2, and sets which video properties the DVD shrinking process
           should optimize the output for, smoothness (fluid motion, but blurry image) or sharpess
           (sharp image, but more choppy motion).




5. Now click on the "Backup Options" tab.




                                          DVD Shrink - Backup Options




   The options that you can select are:

       o   Run backup in low priority mode - select this option if you plan on using other
           applications while DVD Shrink is shrinking.

       o   Shutdown computer ... - select this option if you want DVD Shrink to shutdown your
           computer after it has finished shrinking.

       o   You can also select a sound file to play when DVD Shrink finishes shrinking.
6. Finally, click on the "Burn Settings" tab (only visible when Nero is installed). The options here will
   only be available if you chose the burn straight to disc or create ISO image options. You can specify
   a volume label for the burned disc or image, and in the case of an burned disc, you can specify
   some additional options.




                                  DVD Shrink - Burn Settings for ISO Images




                             DVD Shrink - Burn Settings for Stright to Disc Burns




    The options are:

        o   Burn Speed - select the burn speed to matches your drive/media's maximum allowed
            speed.

        o   Book type DVD-ROM - this option makes DVD players recognise your DVD+R/RW discs are
            a DVD-ROM, and hence improves compatibility with players that don't fully support
            DVD+R/RW. This option may only work with a selected range of DVD burners that support
            bit-setting (eg. Ricoh).

        o   Burn at least 30mm - this is again a compatibility option for DVD+R/RW drives




    Press "OK" when you are ready to start the shrinking process, which may take quite a while,
    depending on your CPU and the length of the movie (and whether you have selected deep analysis
    or not).
7. The encoding window will now show up with an estimated completion time. You can select the
   "Enable Video Preview" option if you wish to see a preview of what's being re-encoded currently -
   deselect this if you want to speed up the encoding a bit. Remember that if you selected deep
   analysis, then the first "Time Remaining" display is for the analysis, and then the shrinking process
   will take roughly the same amount of time again.




                                    DVD Shrink - Deep Analysis or Encoding




    When it's all done, DVD Shrink should show the following screen:




                                        DVD Shrink - Backup Completed




8. If you selected the burn straight to disc option, then you're finished with this guide/tutorial. If you
   selected "Create ISO Image" without the "burn with DVD Decrypter" option, then proceed to the
   Burn Image section whenever you need to burn the DVD Shrink created image. If you selected the
   Hard Disk Folder option, then proceed to the Create and Burn Image section.




                                      Create and Burn Image

 1. Before we make an image, you should make sure the backup DVD Shrink has made is in fact
    working properly. You can do this by using a software DVD player like the latest versions of
    PowerDVD or WinDVD, both of which supports playback of DVD files from the hard-disk.
    Only continue on if the disc is working perfectly, otherwise, DVD Shrink may not have been
     setup properly, or it doesn't work for your particular DVD (and please make use of the bug
                                  report forum to report this problem).

     2. Start ImgTool Classic. If you are using ImgTool Classic for the first time, you will be
                                presented with the following window:




                                           ImgTool Classic



  (if you lose focus on this window, then the only way you can bring it back is to minimize all
                                      your other windows).

                                          The options are:

    o       Split image into 1GB chunks - select this option if you are using a FAT32 system (eg.
                                            Windows 9x/Me)

        o    Burn generated image using DVD Decrypter - make sure this option is selected.
             Then, use the "EXE file" button to load in the DVD Decrypter EXE file. Also make
                         sure you specify the drive letter of your DVD burner drive.



 When you have finished setting up ImgTool Classic for the first time, press the "Save" button
 to save your settings. You can always re-configure these settings from the "Settings" menu in
                                       ImgTool Classic.

3. ImgTool Classic should now start for real. ImgTool Classic is very easy to use, so for the
  "Source Directory" box, load in your DVD Shrink created backup folder (if the DVD Shrink
    created VOB files are in g:\temp\VIDEO_TS, then load in g:\temp). Similarly, specify a
    location for the output file (an DVD image file in .ISO format that will be used by DVD
   Decrypter to burn your backup). For "Volume ID", specify a name you would like for the
                                          image/disc.
                                            ImgTool Classic



    All that's left to do now is to ensure your blank disc is inserted into your DVD burner drive,
              and then, press the "Image" button to start the image and burning process.

4. ImgTool will then finish creating the image and use DVD Decrypter to burn your backup disc,
                and you're now finished with this, hopefully not too painful, guide.




                                          Burn Image

 1. We'll now burn the DVD image file(s). Insert a blank DVD disc in your DVD writer drive.
             Start DVD Decrypter. From the "Mode" menu, select "ISO" -> "Write".




                                    Selecting the ISO Write mode



2. Now use the    icon to load in your .iso image file. Make sure the "destination" selected is your
                           DVD recorder drive. Settings should be set to :

                                      o    Data Type : Mode1/2048
                                          o Write Mode : DVD
                                          o Write Speed : MAX
        3. Now click on the large "Write" button to start the writing process. DVD Decrypter will now
                                  write your image file(s) to your blank DVD.




                                  Start the DVD writing by clicking on this button



                                                4. We're done!!




                                 Guide Archive : DVD Shink (1.x) Guide
Below is an archived version of the previous version of the DVD Shrink Guide (for DVD Shrink 1.x).

There are two versions of the DVD Shrink (1.x) Guide - please select a version :

        Using the Built-in Decrypter - Uses the built-in DVD decryption feature of DVD Shrink to make
         backups

        Using an External Decrypter - Uses an additional piece of software, DVD Decrypter, to decrypt the
         DVD prior to using DVD Shrink to make backups




                   Using the Built-in Decrypter
This method involves using DVD Shrink's built-in DVD decryption engine. The problem with using the built-in
decrypter, as opposed to an external DVD ripper like DVD Decrypter, is that DVD Shrink's decrypter does
not support all the necessary DVD ripping features, such as Macrovision/RCE ripping. It will also access your
DVD-ROM drive during the entire shrinking process, which may reduce the lifetime of your DVD laser (or at
least make your DVD-ROM drive pretty hot). Using DVD Shrink's built-in decrypter will mean less hard-disk
space is required (since you won't need to copy the entire DVD to your hard-drive first). If you prefer to use
an external DVD ripper, please refer to this method.

The shrinking process will reduce the quality of the movie (that's where the file size reduction comes from).
If you want to keep the original quality of the DVD, then you can use this method to split your 9.4 GB DVD
onto 2 4.7 GB DVD recordables.

While quality has been reduced, the content of the DVD (eg. subtitles, extras) can be left untouched. It is
also possible to select which part of the DVD gets "shrunk" and which remains the same (eg. shrink the
extras, but keep the movie untouched).

Okay, let's start ...



Requirements :
                  Operating System capable of handling large files (Windows 2000/XP) - not required if you
                 want to burn the DVD without making an image using Nero Burning ROM (see Step 5);
                  4.38 GB of free hard-drive space
                  1 x blank DVD.


Software Downloads :
              DVD Shrink 1.03 (Mirror 1 | Mirror 2)
              DVD ImgTool (ImgTool 0.89)
               DVD Decrypter
               Optional : Nero Burning ROM


Summary of procedures :

          1. DVD shrinking in DVD Shrink - Use DVD Shrink to reduce the size of the DVD to fit into one
             single DVD±Rs;

          2. Creating the DVD image using ImgTool - Creating an image of the DVD Shrink-ed DVD for
             burning;

          3. Burning the DVD using DVD Decrypter - We go back to DVD Decrypter for the final step by
             burning the image file created in the previous step onto a blank DVD.




Step 1 : DVD shrinking in DVD Shrink

          1. Start DVD Shrink.

          2. Select the big "DVD Drive" button to select "DVD mode", which basically means that we will
             be "shrinking" files directly from the original DVD. From the drop down menu on the right,
             select the drive which contains your DVD movie.




                                      Selecting DVD mode and loading in your DVD




          3. Now we will select the target size of the shrinking process (that is, what is the maximum file
             size that the DVD Shrink-ed files can be). Most DVD recordables are 4.7G (4.38 GB). Some
             older DVD recordables (DVD-R 1.0) can only record to 3.95G, and you can also define a
             custom size for the target by selecting the "Custom" option and entering a custom GB
             (remember : 1 GB = 1024 MB) value. For this tutorial, I have selected 4.7G (4.38 GB) as
             the target size. When you have finished, press the "Next" button.

          4. Select the big "Re-encode" button, which will do the shrinking we require. The graphics at
             the top shows the current size of the ripped DVD files. The green part shows what will fit
             within your target size, while the red part obviously shows how much is over the target size.
             As you can see from the screenshot below, our ripped files are almost 6.5 GB in size, while
             our target size is only 4.38 GB. So basically, our goal is to shrink our 6.5 GB DVD to 4.38
             GB.
                                       Selecting Re-encode mode




5. DVD Shrink will now scan through all your ripped files and work out how much compression
   can be achieved. DVD Shrink defines compression as "levels". A low level (level 1) will mean
   limited shrinking (higher quality), while a high level will mean greater shrinking (at the
   expense of quality). There are currently 8 levels, and after scanning through all your files,
   DVD Shrink should now show the file size each level will shrink to. What we want to do here
   is to select a level that is nearest and below our target size. Since the target size I selected
   in the previous step was 4.38 GB, the target level that is nearest and below this target size
   is level 7, which probably won't give the best quality.




                                     Selecting a compression level




    The screenshot above show that I have selected level 7 - note that this level will apply it to
    *all* of the content on the DVD. DVD Shrink also allows you to select specify different
    compression levels for different parts of the movie (eg. menus at highest compression,
    movie at lowest compression and extras somewhere in between). Instructions on how to do
    this are shown below, but if you are happy with defining a single compression level for *all*
    of the content, then press "Next" to continue.

    Optional : Customizing compression levels for different streams

    First of all, click on the "Customize Streams" button to open the "Advanced Stream
    Selection" window.



                                          Customize Streams
DVD Shrink allows you to specify a custom compression level for each VTS set. A VTS set
can contain a range of different content, for example, a single VTS set may contain 2
trailers, 3 teasers and a featurette. Usually, the main movie in contained in a single VTS set
(see Important #1 notice - for our example, the main movie is located in VTS set 1). Each
VTS set will have a menu, and the actual movie (or set of movies). Each movie may also
have a set of audio and subpicture (subtitle) streams.




                               The structure of a typical VTS set




The key aim here is probably to heavily shrink (by selecting a higher compression level) for
all the menu and extra objects, remove any unwanted audio/subpicture streams and try to
keep the main movie at the highest quality by selecting a lower compression level (or no
compression at all).

The "option" menu within the "Advanced Stream Selection" window allows you to select
what is expanded and shown in the tree style representation of the DVD VTS structure. You
can also manually expand/collapse any branch by clicking on the various items using your
mouse.

If you have trouble knowing which VTS set contains what, there is a preview option that you
can use within DVD Shrink. Next to the "No Compression" option, there is a little "Play" icon.
Clicking on it will allow you to playback the VTS set.




                                        Preview Window

Okay, let's get started. First, I selected all compression level 8 for the video streams of all
VTS sets. Then, I selected level 3 compression for VTS set 1 (the main movie) and
deselected two of the alternative audio streams, which equates to a total DVD size of 4.18
GB (selecting level 2 compressions means 4.51 GB, which is over our target file size). This
means that we can still afford to lower the compression level of another VTS set, and I have
decided to lower the compression level of VTS set 4 (which contains a documentary for the
movie) to level 1, which brings the the total DVD size to 4.31 GB. While further optimization
along these lines can be achieved, I am satisfied with the 4.31 GB file size.

When you are satisfied, press the "OK" button. You'll notice now that DVD Shrink has set the
"Encoding Level" to "Custom Streams", and the "Expected Size" is now 4.31 GB. Press
"Next" to continue.
                                Selecting a custom compression level

6. We'll now select where to output the DVD Shrink-ed DVD files. You may have to manually
   create a new directory to put all the newly DVD Shrink-ed files into. You can change the
   "Target DVD Regions" to select which region the DVD Shrink-ed DVD files will have (by
   default, all regions are selected to make a region-free backup). The "Provider ID" allows you
   to set who produced this backup - add your name, your cat's name, whatever ...

   Press "Next" when you are ready to start the shrinking process, which may take an hour,
   maybe less.




                                            Target options




7. The encoding window will now show up with an estimated completion time. You can select
   the "Video Preview" option if you wish to see a preview of what's being re-encoded
   currently. When DVD Shrink finishes, you can close DVD Shrink and move on to the next
   sections, which deal with burning the DVD Shrink-ed DVD files.
Step 2 : Creating an image of the DVD Shrink-ed DVD for burning

          1. Note that the latest version of ImgTools, used in this step, has DVD burning capabilities, but
             requires the commercial Nero Burning ROM to be installed. Because this guide promises to
             be one that uses free tools whenever available, we'll not use ImgTools to burn the DVD, but
             rather, we'll use it to make DVD image files after which we'll use DVD Decrypter to burn the
             DVD.

          2. Before we make an image, you should make sure the "discs" you've made are in fact
             working properly. You can do this by using a software DVD player like the latest versions of
             PowerDVD or WinDVD, both of which supports playback of DVD files from the hard-disk.
             Only continue on if the disc is working perfectly, otherwise, go back to the step 3 and try to
             figure out if you've missed copying a file or something similar. If there is something wrong
             with playback, then this is most likely due to missing files - try copying the missing files to
             the disc that doesn't play and try to find out what the exact problem is.

          3. The .IMG image file produced will most likely be larger than 4 GB in size. Windows 98/Me
             have problems with single files of larger than 4 GB, and so, it is essential that you do this
             step under an operating system capable of handling large files (Windows 2000/XP). You can
             by-pass this problem by burning the 'disc1' and 'disc2' directories without making an image
             file, eg. by using the "DVD" recording profile under Nero Burning ROM (instructions are not
             provided here, but it is very straight foward for anyone who has used Nero prior).

          4. Start ImgTool. Press the "..." button and load in your 'disc1' and 'disc2' directories (eg. if
             your backup VOB files are stored in f:\disc1\video_ts\, then load in f:\disc1).

              From the "Drive" drop down box, select the first not used drive letter (on my computer,
              drive i: is not used yet). Click on the "Make Drive" button, which will make a virtual drive
              that will contain the contents of your 'disc1' or 'disc2' directory (think of this drive as a
              "virtual DVD disc").




                                                        Prepare Drive




          5. Now click on the "DVD Image" button. This should open a new window. Load in the "virtual
             drive" you just created in the step above (again, drive i: on my computer) for the "DVD
             Drive" entry. And then choose a location for the output file (make sure you have enough
             free disk space) for the "Output Image File" entry. Last, choose a suitable label name for the
             disc you will be creating.




                                                       Image Settings
           6. Finally, check the "Create Disc Image" checkbox to start creating the image files (.img files).
              This could take a while (and a lot of hard-disk space). After the image has been created,
              press "Cancel" and click on the "Delete Drive" button to remove your virtual drive.




Step 3 : Burning the DVD using DVD Decrypter

           1. We'll now burn the DVD image file(s). Insert a blank DVD disc in your DVD writer drive.
              Start DVD Decrypter. From the "Mode" menu, select "ISO" -> "Write".




                                                Selecting the ISO Write mode




           2. Now use the   icon to load in your .img image file. Make sure the "destination" selected is
              your DVD recorder drive. Settings should be set to :

                   o   Data Type : Mode1/2048
                   o   Write Mode : DVD
                   o   Write Speed : MAX




           3. Now click on the large "Write" button to start the writing process. DVD Decrypter will now
              write your image file(s) to your blank DVD.




                                       Start the DVD writing by clicking on this button




           4. We're done!!




                 Using an External Decrypter
This method involves using DVD Decrypter to first rip/copy the DVD movie to your hard-drive, and then
using DVD Shrink to shrink the 9.4G DVD so that it will fit onto one 4.7G DVD recordable. While DVD Shrink
includes a built-in DVD decrypter, it does not support all the necessary DVD ripping features, such as
Macrovision/RCE ripping. It will also access your DVD-ROM drive during the entire shrinking process, which
may reduce the lifetime of your DVD laser (or at least make your DVD-ROM drive pretty hot). Using DVD
Shrink's built-in decrypter will mean less hard-disk space is required (since you won't need to copy the
entire DVD to your hard-drive first), so if you wish to use DVD Shrink's built-in decrypter, please refer to
this method.

Fact #1 : DVD recordables are measured in G where 1G = 1,000,000,000 (1 billion) bytes. This is opposed
to GB, where 1 GB = 1073741824 bytes (1 GB = 1024 MB ; 1 MB = 1024 KB ; 1 KB = 1024 bytes). So a
4.7G DVD-R is actually 4.38 GB. This article will use both G and GB notations, and please note that the use
 of these notations within DVD Shrink are sometimes wrong.

 The shrinking process will reduce the quality of the movie (that's where the file size reduction comes from).
 If you want to keep the original quality of the DVD, then you can use this method to split your 9.4G DVD
 onto 2 4.7G DVD recordables.

 While quality has been reduced, the content of the DVD (eg. subtitles, extras) can be left untouched. It is
 also possible to select which part of the DVD gets "shrunk" and which remains the same (eg. shrink the
 extras, but keep the movie untouched).

 Okay, let's start ...



 Requirements :
                   Operating System capable of handling large files (Windows 2000/XP) - not required if you
                  want to burn the DVD without making an image using Nero Burning ROM (see Step 5);
                   14 GB of free hard-drive space (up to 8.76 GB for ripping DVD, up to an additional 4.38
                  GB for backup disc)
                   1 x blank DVD (4.7G).


 Software Downloads :

               DVD ImgTool (ImgTool 0.89)
               Optional : Nero Burning ROM


 Summary of procedures :

              1. Rip the entire DVD using DVD Decrypter - Rip/copy all the files on the DVD using DVD
                 Decrypter to your hard-drive;

              2. DVD shrinking in DVD Shrink - Use DVD Shrink to reduce the size of the DVD to fit into one
                 single DVD±Rs;

              3. Creating the DVD image using ImgTool - Creating an image of the DVD Shrink-ed DVD for
                 burning;

              4. Burning the DVD using DVD Decrypter - We go back to DVD Decrypter for the final step by
                 burning the image file created in the previous step onto a blank DVD.




 Step 1 : Rip the entire DVD using DVD Decrypter

i.       Insert the DVD you plan to backup. Start DVD Decrypter.

            ii.   From the "Mode" menu, select the "File" mode (or press the "F" shortcut key). This should
                  load the DVD and display all the files on the DVD in the window on the right hand side.

                  Important #1 : You need to remember which title set and files contains the main movie.
                  The main movie's title set and it's files are highlighted by DVD Decrypter upon loading
                  (sometimes not all the files in the set are highlighted, since they may not be part of the
                  movie). In the picture below, the highlighted title set is VTS_01 (although VTS_01_0.VOB is
                  not highlighted and not included in the set).
                      Ripping in File Mode - highlighted files contains main movie




   Now highlight all the files (we want to rip every single file on the DVD) by using the mouse,
   or pressing the "CTRL-A" shortcut key.


iii.        Now change the destination of the output file by clicking on the   icon.

   Recommendation : I recommend that you rip the DVD to a folder of its own, as opposed to
   ripping the files into a folder where files already exists.




       Selecting the output destinatination - make sure there's enough hard-disk space, which is
                                      not the case in this picture




iv.         This step is optional. We can change some of the settings for DVD Decrypter to
   specify the ripping options. To do this, from the "Tools" menu, select "Settings". Then, go to
   the "File Mode" section.




                                    Selecting the File Mode options




   The options that are of interest are :

   a.       Remove IFO/BUP RC Protection - removes region protection from the copied
   DVD
                    b.   Remove IFO/BUP RCE Protection - removed RCE protection (an advanced form
                         of region protection) from the copied DVD
                    c.   Remove PUOs - some DVD movies prevent certain actions to be taken at certain
                         time (eg. you can't change the subtitles while the movie is playing, or your can't
                         skip past the copyright message). This option will remove these limitations.




            v.           Now click on the large "Decrypt" button to start the copying process. DVD Decrypter
                 will now copy all the files on your DVD to your hard-drive. You can close down DVD
                 Decrypter once it has finished ripping all the files.




                                         Start the Decryption by clicking on this button




Step 2 : DVD shrinking in DVD Shrink

          1. Start DVD Shrink.

          2. Select the big "Files" button to select "file mode", which basically means that we will be
             "shrinking" files that have already been ripped from the hard-drive. Click on the "Browse"
             button and load in the VIDEO_TS.IFO file of the DVD movie you just ripped.




                                      Selecting File mode and loading in your ripped files




          3. Now we will select the target size of the shrinking process (that is, what is the maximum file
             size that the DVD Shrink-ed files can be). Most DVD recordables are 4.7G (4.38 GB). Some
             older DVD recordables (DVD-R 1.0) can only record to 3.95G, and you can also define a
             custom size for the target by selecting the "Custom" option and entering a custom GB
             (remember : 1 GB = 1024 MB) value. For this tutorial, I have selected 4.7G (4.38 GB) as
             the target size. When you have finished, press the "Next" button.

          4. Select the big "Re-encode" button, which will do the shrinking we require. The graphics at
             the top shows the current size of the ripped DVD files. The green part shows what will fit
             within your target size, while the red part obviously shows how much is over the target size.
             As you can see from the screenshot below, our ripped files are almost 6.5 GB in size, while
             our target size is only 4.38 GB. So basically, our goal is to shrink our 6.5 GB DVD to 4.38
             GB.
                                       Selecting Re-encode mode




5. DVD Shrink will now scan through all your ripped files and work out how much compression
   can be achieved. DVD Shrink defines compression as "levels". A low level (level 1) will mean
   limited shrinking (higher quality), while a high level will mean greater shrinking (at the
   expense of quality). There are currently 8 levels, and after scanning through all your files,
   DVD Shrink should now show the file size each level will shrink to. What we want to do here
   is to select a level that is nearest and below our target size. Since the target size I selected
   in the previous step was 4.38 GB, the target level that is nearest and below this target size
   is level 7, which probably won't give the best quality.




                                     Selecting a compression level




    The screenshot above show that I have selected level 7 - note that this level will apply it to
    *all* of the content on the DVD. DVD Shrink also allows you to select specify different
    compression levels for different parts of the movie (eg. menus at highest compression,
    movie at lowest compression and extras somewhere in between). Instructions on how to do
    this are shown below, but if you are happy with defining a single compression level for *all*
    of the content, then press "Next" to continue.

    Optional : Customizing compression levels for different streams

    First of all, click on the "Customize Streams" button to open the "Advanced Stream
    Selection" window.



                                          Customize Streams
DVD Shrink allows you to specify a custom compression level for each VTS set. A VTS set
can contain a range of different content, for example, a single VTS set may contain 2
trailers, 3 teasers and a featurette. Usually, the main movie in contained in a single VTS set
(see Important #1 notice - for our example, the main movie is located in VTS set 1). Each
VTS set will have a menu, and the actual movie (or set of movies). Each movie may also
have a set of audio and subpicture (subtitle) streams.




                               The structure of a typical VTS set




The key aim here is probably to heavily shrink (by selecting a higher compression level) for
all the menu and extra objects, remove any unwanted audio/subpicture streams and try to
keep the main movie at the highest quality by selecting a lower compression level (or no
compression at all).

The "option" menu within the "Advanced Stream Selection" window allows you to select
what is expanded and shown in the tree style representation of the DVD VTS structure. You
can also manually expand/collapse any branch by clicking on the various items using your
mouse.

If you have trouble knowing which VTS set contains what, there is a preview option that you
can use within DVD Shrink. Next to the "No Compression" option, there is a little "Play" icon.
Clicking on it will allow you to playback the VTS set.




                                        Preview Window




Okay, let's get started. First, I selected all compression level 8 for the video streams of all
VTS sets. Then, I selected level 3 compression for VTS set 1 (the main movie) and
deselected two of the alternative audio streams, which equates to a total DVD size of 4.18
GB (selecting level 2 compressions means 4.51 GB, which is over our target file size). This
means that we can still afford to lower the compression level of another VTS set, and I have
decided to lower the compression level of VTS set 4 (which contains a documentary for the
movie) to level 1, which brings the the total DVD size to 4.31 GB. While further optimization
along these lines can be achieved, I am satisfied with the 4.31 GB file size. See the
screenshot below to see what I have selected for VTS set 1 and VTS set 4.
                                Selecting a custom compression level




   When you are satisfied, press the "OK" button. You'll notice now that DVD Shrink has set the
   "Encoding Level" to "Custom Streams", and the "Expected Size" is now 4.31 GB. Press
   "Next" to continue.

6. We'll now select where to output the DVD Shrink-ed DVD files. You may have to manually
   create a new directory to put all the newly DVD Shrink-ed files into. You can change the
   "Target DVD Regions" to select which region the DVD Shrink-ed DVD files will have (by
   default, all regions are selected to make a region-free backup). The "Provider ID" allows you
   to set who produced this backup - add your name, your cat's name, whatever ...

   Press "Next" when you are ready to start the shrinking process, which may take an hour,
   maybe less.




                                            Target options
          7. The encoding window will now show up with an estimated completion time. You can select
             the "Video Preview" option if you wish to see a preview of what's being re-encoded
             currently. When DVD Shrink finishes, you can close DVD Shrink and move on to the next
             sections, which deal with burning the DVD Shrink-ed DVD files.




                                                           Encoding




Step 3 : Creating an image of the DVD Shrink-ed DVD for burning

          1. Note that the latest version of ImgTools, used in this step, has DVD burning capabilities, but
             requires the commercial Nero Burning ROM to be installed. Because this guide promises to
             be one that uses free tools whenever available, we'll not use ImgTools to burn the DVD, but
             rather, we'll use it to make DVD image files after which we'll use DVD Decrypter to burn the
             DVD.

          2. Before we make an image, you should make sure the "discs" you've made are in fact
             working properly. You can do this by using a software DVD player like the latest versions of
             PowerDVD or WinDVD, both of which supports playback of DVD files from the hard-disk.

          4. Start ImgTool. Press the "..." button and load in your 'disc1' and 'disc2' directories (eg. if

              From the "Drive" drop down box, select the first not used drive letter (on my computer,
              drive i: is not used yet). Click on the "Make Drive" button, which will make a virtual drive

          5. Now click on the "DVD Image" button. This should open a new window. Load in the "virtual
             drive" you just created in the step above (again, drive i: on my computer) for the "DVD

             free disk space) for the "Output Image File" entry. Last, choose a suitable label name for the
             disc you will be creating.




                                                      Image Settings




          6. Finally, check the "Create Disc Image" checkbox to start creating the image files (.img files).
             This could take a while (and a lot of hard-disk space). After the image has been created,
             press "Cancel" and click on the "Delete Drive" button to remove your virtual drive.




Step 4 : Burning the DVD using DVD Decrypter

          1. We'll now burn the DVD image file(s). Insert a blank DVD disc in your DVD writer drive.
             Start DVD Decrypter. From the "Mode" menu, select "ISO" -> "Write".




                                               Selecting the ISO Write mode




          2. Now use the   icon to load in your .img image file. Make sure the "destination" selected is
             your DVD recorder drive. Settings should be set to :

                  o   Data Type : Mode1/2048
                  o   Write Mode : DVD
                  o   Write Speed : MAX




          3. Now click on the large "Write" button to start the writing process. DVD Decrypter will now
             write your image file(s) to your blank DVD.

          4. We're done!!
                                 Guide Archive : DVD Shink (2.x) Guide
Below is an archived version of the previous version of the DVD Shrink Guide (for DVD Shrink 2.x).

There are two versions of the DVD Shrink (2.x) Guide - please select a version :

       Using the Built-in Decrypter - Uses the built-in DVD decryption feature of DVD Shrink to make
        backups

       Using an External Decrypter - Uses an additional piece of software, DVD Decrypter, to decrypt the
        DVD prior to using DVD Shrink to make backups




                   Using the Built-in Decrypter
This method involves using DVD Shrink's built-in DVD decryption engine. The problem with using the built-in
decrypter, as opposed to an external DVD ripper like DVD Decrypter, is that DVD Shrink's decrypter does
not support all the necessary DVD ripping features, such as Macrovision/RCE ripping. It will also access your
DVD-ROM drive during the entire shrinking process, which may reduce the lifetime of your DVD laser (or at
least make your DVD-ROM drive pretty hot). Using DVD Shrink's built-in decrypter will mean less hard-disk
space is required (since you won't need to copy the entire DVD to your hard-drive first). If you prefer to use
an external DVD ripper, please refer to this method.

The shrinking process will reduce the quality of the movie (that's where the file size reduction comes from).
If you want to keep the original quality of the DVD, then you can use this method to split your 9.4 GB DVD
onto 2 4.7 GB DVD recordables.

While quality has been reduced, the content of the DVD (eg. subtitles, extras) can be left untouched. It is
also possible to select which part of the DVD gets "shrunk" and which remains the same (eg. shrink the
extras, but keep the movie untouched).

Okay, let's start ...



Requirements :
                  Operating System capable of handling large files (Windows 2000/XP) - not required if you
                 want to burn the DVD without making an image using Nero Burning ROM (see Step 5);
                  4.38 GB of free hard-drive space
                  1 x blank DVD.

Summary of procedures :

             1. DVD shrinking in DVD Shrink - Use DVD Shrink to reduce the size of the DVD to fit into one
                single DVD±Rs;

             2. Creating the DVD image using ImgTool - Creating an image of the DVD Shrink-ed DVD for
                burning;

             3. Burning the DVD using DVD Decrypter - We go back to DVD Decrypter for the final step by
                burning the image file created in the previous step onto a blank DVD.
Step 1 : DVD shrinking in DVD Shrink

          1. Start DVD Shrink.

          2. From the "Edit" drop down menu, select "Preferences". In the window that pops up, you can
             configure several of DVD Shrink's options :




                                               DVD Shrink - Preferences




             The options explained :

                 1. Target DVD Size : - this states the target size of the backup you wish to make.
                    Normally, the default option of "DVD-5 (4.7GB)" is what you will need if you plan to
                    make single disc backups. Note that 4.7G in DVD-R notation actually translates to
                    4.38GB in normal computer notation (eg. those that is reported in Windows
                    Explorer) - this is because 1G is equal to 1,000,000,000 bytes, whereas 1GB is equal
                    to 1073741824 bytes (1024 x 1024 x 1024).

                 2. Error Margin (MB) : - this specifies the margin of error that you want DVD Shrink
                    to assume. When you set a target size, DVD Shrink will try to get your DVD within
                    as close to this target size (but always just under it) as possible. However,
                    prediction is involved, and the prediction isn't always right. The error margin will
                    make DVD Shrink aim for a lower target size ("Real" target size = Target Size - Error
                    Margin), and hence, avoid disk space over-runs.

                 3. Play video preview whenever selection changes - this changes the default
                    behavior of the preview window. Checking this option will automatically playback the
                    preview clip in the preview window, whereas unchecking it will start the preview in
                    pause mode.

                 4. Show Gridlines - this is a graphic interface option, which enables/disables gridlines
                    in the main window panels.

                 5. Hide audio/subpicture streams less than 1MB - this option, when selected,
                    hides small audio/subpicture streams that would otherwise clutter up the DVD
                    Shrink stream view.

                 6. Show overlapping titles combined - overlapping titles will be combined when
                    shown in DVD Shrink.
    Press "OK" when you have finished setting up the DVD Shrink preferences.

3. Click on the "Open Disk" button - this should bring up a new window. From the drop down
   menu, select the drive which contains your DVD movie.




                                       DVD Shrink - Open Disk




4. DVD Shrink will now scan through your DVD and work out how much compression can be
   achieved. It only needs to do this once per DVD.




                                     DVD Shrink - Analysing DVD




5. By default, DVD Shrink should select the "Full Disk" mode for you, which will keep all the
   content on the DVD, but will shrink the contents so that it will fit onto a single DVD
   recordable. This is the mode we want, so if it isn't selected, make sure you press the "Full
   Disk" button.




                                        DVD Shrink - Full Disk




6. Let's take a look at the various panels within DVD Shrink :
                                         DVD Shrink - Views




7. The "Titles View" shows the structure of your DVD. Each DVD has three components :
   Menus, Main Movie and Extras. Each component can have many titles (eg. Extras : trailers,
   TV spots, documentaries ... are all separate titles). The file size, both before and after
   shrinking/compression, is also shown.

   To specify a single compression level for the entire DVD, click and highlight the "DVD" item.
   Otherwise, you can click and highlight any particular component or title to change it's
   compression level individually, which brings us to ...




                                       DVD Shrink - Titles View




8. ... the "Stream View". This panel shows the various streams (eg. video, audio, subtitles) of
   the currently selected DVD, component or title, as well as the compression level you define
   for the currently selected DVD/component/title.
                                       DVD Shrink - Stream View




    DVD Shrink defines compression as "levels". A low level (level 1) will mean limited shrinking
    (higher quality), while a high level will mean greater shrinking (at the expense of quality).
    There are currently 10 levels (plus a "still" level for encoding still frames). Remember back
    to when DVD Shrink scanned through all your files - DVD Shrink did this so it can predict the
    file size each level will shrink to.

    Our goal now is to select a compression level that will bring our DVD under the selected
    target size. We would also need to ensure the picture quality is not too poor, and preferably,
    that the main movie will be higher in quality than the extras.

9. The graphical size bar at the top shows the current size of the ripped DVD files. The green
   part shows what will fit within your target size, while the red part obviously shows how
   much is over the target size. As you can see from the screenshot below, our ripped files are
   6578 MB in size, while our target size is only 4.38 GB. So basically, our goal is to shrink our
   6578 MB DVD to under 4488 MB.



                                         DVD Shrink - Size Bar




    We can achieve our goal by setting the compression levels within the "Stream View", and
    also by deselecting any unwanted streams (eg. removing the "Director's Commentary"
    track, which could save some 400 MB in space). This is the part that I can really help you,
    since each DVD is different. As an example, this is what I have done with the Ice Age
    (Region 4) DVD to shrink it under 4.38GB :




        o   Menus : highest compression level (level 8 and 10)
        o   Main Movie : compression level 5, deselected "Directory's Commentary" audio track
        o   Extras : compression level 8 for long content, and level 9 for short content
                                     DVD Shrink - Shrunk Sizes




   Once the graphical size bar at the top turn completely green, it means that we have reached
   our target size.

10. Now click on the "Backup!" button.




                                         DVD Shrink - Backup




   If the current predicted size of the shrunk DVD is larger than your target size, then you may
   encounter the following screen :




                               DVD Shrink - Target DVD Size Exceeded




   Even if you exceed the target size, you can still backup this DVD - since my shrunk DVD is
   only 5 MB above the target size (actually target size of 4.38 GB minus my set error margin
   of 30 MB), and within the margin of error, I will choose option 2 and backup this DVD to my
   hard-drive.

11. We'll now select where to output the DVD Shrink-ed DVD files (Target Folder). You may
    have to manually create a new directory to put all the newly DVD Shrink-ed files into. You
    can change the "Target DVD Regions" to select which region the DVD Shrink-ed DVD files
    will have (by default, all regions are selected to make a region-free backup). The "Provider
    ID" allows you to set who produced this backup - add your name, your cat's name, whatever
    ...

   Press "OK" when you are ready to start the shrinking process, which may take an hour,
   maybe less.
                                                 DVD Shrink - Backup DVD




          12. The encoding window will now show up with an estimated completion time. You can select
              the "Enable Video Preview" option if you wish to see a preview of what's being re-encoded
              currently. When DVD Shrink finishes, you can close DVD Shrink and move on to the next
              sections, which deal with burning the DVD Shrink-ed DVD files.




                                                   DVD Shrink - Encoding




Step 2 : Creating an image of the DVD Shrink-ed DVD for burning

          1. Note that the latest version of ImgTools, used in this step, has DVD burning capabilities, but
             requires the commercial Nero Burning ROM to be installed. Because this guide promises to
             be one that uses free tools whenever available, we'll not use ImgTools to burn the DVD, but
             rather, we'll use it to make DVD image files after which we'll use DVD Decrypter to burn the
             DVD.

          2. Before we make an image, you should make sure the "discs" you've made are in fact
             working properly. You can do this by using a software DVD player like the latest versions of
             PowerDVD or WinDVD, both of which supports playback of DVD files from the hard-disk.
             Only continue on if the disc is working perfectly, otherwise, go back to the step 3 and try to
             figure out if you've missed copying a file or something similar. If there is something wrong
             with playback, then this is most likely due to missing files - try copying the missing files to
             the disc that doesn't play and try to find out what the exact problem is.

          3. The .IMG image file produced will most likely be larger than 4 GB in size. Windows 98/Me
             have problems with single files of larger than 4 GB, and so, it is essential that you do this
             step under an operating system capable of handling large files (Windows 2000/XP). You can
             by-pass this problem by burning the 'disc1' and 'disc2' directories without making an image
             file, eg. by using the "DVD" recording profile under Nero Burning ROM (instructions are not
             provided here, but it is very straight foward for anyone who has used Nero prior).
          4. Start ImgTool. Press the "..." button and load in your 'disc1' and 'disc2' directories (eg. if
             your backup VOB files are stored in f:\disc1\video_ts\, then load in f:\disc1).

              From the "Drive" drop down box, select the first not used drive letter (on my computer,
              drive i: is not used yet). Click on the "Make Drive" button, which will make a virtual drive
              that will contain the contents of your 'disc1' or 'disc2' directory (think of this drive as a
              "virtual DVD disc").




                                                        Prepare Drive




          5. Now click on the "DVD Image" button. This should open a new window. Load in the "virtual
             drive" you just created in the step above (again, drive i: on my computer) for the "DVD
             Drive" entry. And then choose a location for the output file (make sure you have enough
             free disk space) for the "Output Image File" entry. Last, choose a suitable label name for the
             disc you will be creating.




                                                       Image Settings




          6. Finally, check the "Create Disc Image" checkbox to start creating the image files (.img files).
             This could take a while (and a lot of hard-disk space). After the image has been created,
             press "Cancel" and click on the "Delete Drive" button to remove your virtual drive.




Step 3 : Burning the DVD using DVD Decrypter

          1. We'll now burn the DVD image file(s). Insert a blank DVD disc in your DVD writer drive.
             Start DVD Decrypter. From the "Mode" menu, select "ISO" -> "Write".




                                                Selecting the ISO Write mode




          2. Now use the   icon to load in your .img image file. Make sure the "destination" selected is
             your DVD recorder drive. Settings should be set to :

                  o   Data Type : Mode1/2048
                        o   Write Mode : DVD
                        o   Write Speed : MAX




             3. Now click on the large "Write" button to start the writing process. DVD Decrypter will now
                write your image file(s) to your blank DVD.




                                          Start the DVD writing by clicking on this button




             4. We're done!!




                   Using an External Decrypter
This method involves using DVD Decrypter to first rip/copy the DVD movie to your hard-drive, and then
using DVD Shrink to shrink the 9.4G DVD so that it will fit onto one 4.7G DVD recordable. While DVD Shrink
includes a built-in DVD decrypter, it does not support all the necessary DVD ripping features, such as
Macrovision/RCE ripping. It will also access your DVD-ROM drive during the entire shrinking process, which
may reduce the lifetime of your DVD laser (or at least make your DVD-ROM drive pretty hot). Using DVD
Shrink's built-in decrypter will mean less hard-disk space is required (since you won't need to copy the
entire DVD to your hard-drive first), so if you wish to use DVD Shrink's built-in decrypter, please refer to
this method.

Fact #1 : DVD recordables are measured in G where 1G = 1,000,000,000 (1 billion) bytes. This is opposed
to GB, where 1 GB = 1073741824 bytes (1 GB = 1024 MB ; 1 MB = 1024 KB ; 1 KB = 1024 bytes). So a
4.7G DVD-R is actually 4.38 GB. This article will use both G and GB notations, and please note that the use
of these notations within DVD Shrink are sometimes wrong.

The shrinking process will reduce the quality of the movie (that's where the file size reduction comes from).
If you want to keep the original quality of the DVD, then you can use this method to split your 9.4G DVD
onto 2 4.7G DVD recordables.

While quality has been reduced, the content of the DVD (eg. subtitles, extras) can be left untouched. It is
also possible to select which part of the DVD gets "shrunk" and which remains the same (eg. shrink the
extras, but keep the movie untouched).

Okay, let's start ...



Requirements :
                  Operating System capable of handling large files (Windows 2000/XP) - not required if you
                 want to burn the DVD without making an image using Nero Burning ROM (see Step 5);
                  14 GB of free hard-drive space (up to 8.76 GB for ripping DVD, up to an additional 4.38
                 GB for backup disc)
                  1 x blank DVD (4.7G).

                      DVD Decrypter
                      Optional : Nero Burning ROM


 Summary of procedures :

           1. Rip the entire DVD using DVD Decrypter - Rip/copy all the files on the DVD using DVD
              Decrypter to your hard-drive;

           2. DVD shrinking in DVD Shrink - Use DVD Shrink to reduce the size of the DVD to fit into one
              single DVD±Rs;

           3. Creating the DVD image using ImgTool - Creating an image of the DVD Shrink-ed DVD for
              burning;

           4. Burning the DVD using DVD Decrypter - We go back to DVD Decrypter for the final step by
              burning the image file created in the previous step onto a blank DVD.




 Step 1 : Rip the entire DVD using DVD Decrypter

i.     Insert the DVD you plan to backup. Start DVD Decrypter.

         ii.      From the "Mode" menu, select the "File" mode (or press the "F" shortcut key). This should
                  load the DVD and display all the files on the DVD in the window on the right hand side.

                  Important #1 : You need to remember which title set and files contains the main movie.
                  The main movie's title set and it's files are highlighted by DVD Decrypter upon loading
                  (sometimes not all the files in the set are highlighted, since they may not be part of the
                  movie). In the picture below, the highlighted title set is VTS_01 (although VTS_01_0.VOB is
                  not highlighted and not included in the set).




                                     Ripping in File Mode - highlighted files contains main movie




                  Now highlight all the files (we want to rip every single file on the DVD) by using the mouse,
                  or pressing the "CTRL-A" shortcut key.


               iii.        Now change the destination of the output file by clicking on the   icon.

                  Recommendation : I recommend that you rip the DVD to a folder of its own, as opposed to
                  ripping the files into a folder where files already exists.
                   Selecting the output destinatination - make sure there's enough hard-disk space, which is
                                                  not the case in this picture




           iv.         This step is optional. We can change some of the settings for DVD Decrypter to
              specify the ripping options. To do this, from the "Tools" menu, select "Settings". Then, go to
              the "File Mode" section.




                                                  Selecting the File Mode options




                 The options that are of interest are :

                 a.       Remove IFO/BUP RC Protection - removes region protection from the copied
                 DVD
                    b.    Remove IFO/BUP RCE Protection - removed RCE protection (an advanced form
                          of region protection) from the copied DVD
                     c.   Remove PUOs - some DVD movies prevent certain actions to be taken at certain
                          time (eg. you can't change the subtitles while the movie is playing, or your can't
                          skip past the copyright message). This option will remove these limitations.




            v.           Now click on the large "Decrypt" button to start the copying process. DVD Decrypter
                 will now copy all the files on your DVD to your hard-drive. You can close down DVD
                 Decrypter once it has finished ripping all the files.




                                          Start the Decryption by clicking on this button




Step 2 : DVD shrinking in DVD Shrink

          1. Start DVD Shrink.

          2. From the "Edit" drop down menu, select "Preferences". In the window that pops up, you can
             configure several of DVD Shrink's options :
                                     DVD Shrink - Preferences




   The options explained :

       1. Target DVD Size : - this states the target size of the backup you wish to make.
          Normally, the default option of "DVD-5 (4.7GB)" is what you will need if you plan to
          make single disc backups. Note that 4.7G in DVD-R notation actually translates to
          4.38GB in normal computer notation (eg. those that is reported in Windows
          Explorer) - this is because 1G is equal to 1,000,000,000 bytes, whereas 1GB is equal
          to 1073741824 bytes (1024 x 1024 x 1024).

       2. Error Margin (MB) : - this specifies the margin of error that you want DVD Shrink
          to assume. When you set a target size, DVD Shrink will try to get your DVD within
          as close to this target size (but always just under it) as possible. However,
          prediction is involved, and the prediction isn't always right. The error margin will
          make DVD Shrink aim for a lower target size ("Real" target size = Target Size - Error
          Margin), and hence, avoid disk space over-runs.

       3. Play video preview whenever selection changes - this changes the default
          behavior of the preview window. Checking this option will automatically playback the
          preview clip in the preview window, whereas unchecking it will start the preview in
          pause mode.

       4. Show Gridlines - this is a graphic interface option, which enables/disables gridlines
          in the main window panels.

       5. Hide audio/subpicture streams less than 1MB - this option, when selected,
          hides small audio/subpicture streams that would otherwise clutter up the DVD
          Shrink stream view.

       6. Show overlapping titles combined - overlapping titles will be combined when
          shown in DVD Shrink.




   Press "OK" when you have finished setting up the DVD Shrink preferences.

3. Click on the "Open Files" button and load in the VIDEO_TS.IFO file of the DVD movie you
   just ripped.
                                       DVD Shrink - Open Files




4. DVD Shrink will now scan through your DVD and work out how much compression can be
   achieved.




                                     DVD Shrink - Analysing DVD




5. By default, DVD Shrink should select the "Full Disk" mode for you, which will keep all the
   content on the DVD, but will shrink the contents so that it will fit onto a single DVD
   recordable. This is the mode we want, so if it isn't selected, make sure you press the "Full
   Disk" button.

6. Let's take a look at the various panels within DVD Shrink :
                                         DVD Shrink - Views




7. The "Titles View" shows the structure of your DVD. Each DVD has three components :
   Menus, Main Movie and Extras. Each component can have many titles (eg. Extras : trailers,
   TV spots, documentaries ... are all separate titles). The file size, both before and after
   shrinking/compression, is also shown.

   To specify a single compression level for the entire DVD, click and highlight the "DVD" item.
   Otherwise, you can click and highlight any particular component or title to change it's
   compression level individually, which brings us to ...




                                       DVD Shrink - Titles View




8. ... the "Stream View". This panel shows the various streams (eg. video, audio, subtitles) of
   the currently selected DVD, component or title, as well as the compression level you define
   for the currently selected DVD/component/title.
                                       DVD Shrink - Stream View




    DVD Shrink defines compression as "levels". A low level (level 1) will mean limited shrinking
    (higher quality), while a high level will mean greater shrinking (at the expense of quality).
    There are currently 10 levels (plus a "still" level for encoding still frames). Remember back
    to when DVD Shrink scanned through all your files - DVD Shrink did this so it can predict the
    file size each level will shrink to.

    Our goal now is to select a compression level that will bring our DVD under the selected
    target size. We would also need to ensure the picture quality is not too poor, and preferably,
    that the main movie will be higher in quality than the extras.

9. The graphical size bar at the top shows the current size of the ripped DVD files. The green
   part shows what will fit within your target size, while the red part obviously shows how
   much is over the target size. As you can see from the screenshot below, our ripped files are
   6578 MB in size, while our target size is only 4.38 GB. So basically, our goal is to shrink our
   6578 MB DVD to under 4488 MB.



                                         DVD Shrink - Size Bar




    We can achieve our goal by setting the compression levels within the "Stream View", and
    also by deselecting any unwanted streams (eg. removing the "Director's Commentary"
    track, which could save some 400 MB in space). This is the part that I can really help you,
    since each DVD is different. As an example, this is what I have done with the Ice Age
    (Region 4) DVD to shrink it under 4.38GB :




        o   Menus : highest compression level (level 8 and 10)
        o   Main Movie : compression level 5, deselected "Directory's Commentary" audio track
        o   Extras : compression level 8 for long content, and level 9 for short content
                                     DVD Shrink - Shrunk Sizes




   Once the graphical size bar at the top turn completely green, it means that we have reached
   our target size.

10. Now click on the "Backup!" button.




                                         DVD Shrink - Backup




   If the current predicted size of the shrunk DVD is larger than your target size, then you may
   encounter the following screen :




                               DVD Shrink - Target DVD Size Exceeded




   Even if you exceed the target size, you can still backup this DVD - since my shrunk DVD is
   only 5 MB above the target size (actually target size of 4.38 GB minus my set error margin
   of 30 MB), and within the margin of error, I will choose option 2 and backup this DVD to my
   hard-drive.

11. We'll now select where to output the DVD Shrink-ed DVD files (Target Folder). You may
    have to manually create a new directory to put all the newly DVD Shrink-ed files into. You
    can change the "Target DVD Regions" to select which region the DVD Shrink-ed DVD files
    will have (by default, all regions are selected to make a region-free backup). The "Provider
    ID" allows you to set who produced this backup - add your name, your cat's name, whatever
    ...

   Press "OK" when you are ready to start the shrinking process, which may take an hour,
   maybe less.

          12. The encoding window will now show up with an estimated completion time. You can select
              the "Enable Video Preview" option if you wish to see a preview of what's being re-encoded
              currently. When DVD Shrink finishes, you can close DVD Shrink and move on to the next
              sections, which deal with burning the DVD Shrink-ed DVD files.

Step 3 : Creating an image of the DVD Shrink-ed DVD for burning

          1. Note that the latest version of ImgTools, used in this step, has DVD burning capabilities, but
             requires the commercial Nero Burning ROM to be installed. Because this guide promises to
             be one that uses free tools whenever available, we'll not use ImgTools to burn the DVD, but
             rather, we'll use it to make DVD image files after which we'll use DVD Decrypter to burn the
             DVD.

          2. Before we make an image, you should make sure the "discs" you've made are in fact
             working properly. You can do this by using a software DVD player like the latest versions of
             PowerDVD or WinDVD, both of which supports playback of DVD files from the hard-disk.
             Only continue on if the disc is working perfectly, otherwise, go back to the step 3 and try to
             figure out if you've missed copying a file or something similar. If there is something wrong
             with playback, then this is most likely due to missing files - try copying the missing files to
             the disc that doesn't play and try to find out what the exact problem is.

          3. The .IMG image file produced will most likely be larger than 4 GB in size. Windows 98/Me
             have problems with single files of larger than 4 GB, and so, it is essential that you do this
             step under an operating system capable of handling large files (Windows 2000/XP). You can
             by-pass this problem by burning the 'disc1' and 'disc2' directories without making an image
             file, eg. by using the "DVD" recording profile under Nero Burning ROM (instructions are not
             provided here, but it is very straight foward for anyone who has used Nero prior).
          4. Start ImgTool. Press the "..." button and load in your 'disc1' and 'disc2' directories (eg. if
             your backup VOB files are stored in f:\disc1\video_ts\, then load in f:\disc1).

              From the "Drive" drop down box, select the first not used drive letter (on my computer,
              drive i: is not used yet). Click on the "Make Drive" button, which will make a virtual drive
              that will contain the contents of your 'disc1' or 'disc2' directory (think of this drive as a
              "virtual DVD disc").




                                                        Prepare Drive




          5. Now click on the "DVD Image" button. This should open a new window. Load in the "virtual
             drive" you just created in the step above (again, drive i: on my computer) for the "DVD
             Drive" entry. And then choose a location for the output file (make sure you have enough
             free disk space) for the "Output Image File" entry. Last, choose a suitable label name for the
             disc you will be creating.




                                                       Image Settings




          6. Finally, check the "Create Disc Image" checkbox to start creating the image files (.img files).
             This could take a while (and a lot of hard-disk space). After the image has been created,
             press "Cancel" and click on the "Delete Drive" button to remove your virtual drive.




Step 4 : Burning the DVD using DVD Decrypter

          1. We'll now burn the DVD image file(s). Insert a blank DVD disc in your DVD writer drive.
             Start DVD Decrypter. From the "Mode" menu, select "ISO" -> "Write".




                                                Selecting the ISO Write mode




          2. Now use the   icon to load in your .img image file. Make sure the "destination" selected is
             your DVD recorder drive. Settings should be set to :

                  o   Data Type : Mode1/2048
       o   Write Mode : DVD
       o   Write Speed : MAX




3. Now click on the large "Write" button to start the writing process. DVD Decrypter will now
   write your image file(s) to your blank DVD.




                           Start the DVD writing by clicking on this button




4. We're done!!
