DVD Shrink will not remove any encryptions, for that you have to use a prog such as AnyDVD and run that in the background. Then you can proceed to use DVD Shrink in the normal manner. AnyDVD is free for a trial period of 21 days and available at slysoft site as is Clone DVD2, also used for backing up DVDs
Shrink can't remove the newer ones and will give you a free different errors. You can also download dvdfab decrypter(free)this will also remove the newer copy protections that shrink can't like Sony's ARccOS. Rip the files then process thru shrink as usual. Here's a link: http://dvdidle.com/free.htm
