DVD Shrink can rip DVD's, but can fall over on some DVD copy protection, thats why you're better off using DVD Decrypter (latest version is 3.1.2.0) that has yet to fail ripping any DVD for me
Also,set the option 'Don't use Nero' and let DVD Shrink use DVD Decrypter as teh burning engine. Personally I have found Nero is terrible at burning DVD videos (BUT this is what I have found through personal experiences)
Have a quick look at my guide if you're not 100% sure what settings to enable DVD Decrypter to burn as well as rip
