Another alternative is DVD Shrink . It is able to rip DVD to your hard drive as video files or as an ISO image. Then you can burn the output files by integrating with Nero or other DVD burning software. What makes this program unique is its ability to compress DVD data to the standard 4.7-gig DVD. You will rarely, if ever, notice any decrease in video quality.
The latest version is 3.2.0.15 built in July 2004. The UI looks “unfashionable” today. But personally, I like its considerate and friendly design very much. It lists the DVD structure including Menus, Main Movie and Unreferenced Materials. This means you can easily choose which parts of the DVD you want to include for ripping and shrinking. It’s a nice feature for you to leave out unwanted bonus features, audio data for languages, etc.
DVD Shrink offers built-in decryption algorithms to “read” encrypted DVDs. Unfortunately, as it stopped updating in 2004, some recent copy protection methods are not supported. I tested Transformers 2 and UP. It freezed when analyzing the DVD info. Non-encrypted DVDs work perfectly.
