***Please take note that DVD Shrink is simply a DVD ripper and compressor. You cannot use DVD Shrink to burn DVDs. You need additional DVD burning software to extract the DVD files on your hard drive to a DVD-R.***
Compressor
When DVD Shrink is launched you can instruct it to locate a DVD in your disc drive or open a previously ripped VOB or ISO image file located on your hard drive. DVD Shrink will read all the files on the DVD including menus, extras, audio tracks and subtitles, and compress them accordingly. Longer movies and those loaded with special features would experience significant compression, resulting in a lower quality copy. Major motion pictures will typically have more than 50 percent compression.
The more a movie is compressed the less quality the copy retains. To lessen the compression you can remove additional audio tracks or special features. This process works the same with ripped VOB files, ISO files and DVDs in the disc drive.
Ripping and Imaging
When you open a DVD using DVD Shrink, DVD Shrink will ignore most common protections and encryptions and display the files located on the DVD movie. Unlike some other, popular DVD rippers, DVD Shrink does not display the VOB files. It simply locates the DVD’s menus, movie and extras. You can then rip the entire DVD or an ISO image of the DVD to your hard drive.
Re-authoring
In re-authoring mode, you can choose exactly which portions of the DVD you would like to keep. The less you choose to place on the DVD copy the less compression the copy requires. For example, if you were to only copy the main movie with only one audio track there would be approximately 15 percent compression, opposed to the usual 50 percent.
Unfortunately, retaining original DVD menus using DVD Shrink is tricky. You cannot retain full menu function when in re-author mode. When burning the menus will act as a image screen. The only way to keep the DVD menus is to copy the entire DVD movie.
