Hey, don't intend to boast but I've noticed a lot of people backing up the same movies as myself including "Children of Men" and "Happy Feet" with various problems and others mentioned. I don't seem to encounter any problems using DVD Shrink, infact it's never, ever failed me. I use a process of Decrypting my DVD with DVD Decrypter to the hard drive, then shrinking these files to 4.3gb with DVD Shrink then burning with Nero. Anything decrypted with DVD Decrypter has never had a problem with DVD Shrink and anything compressed with DVD Shrink has never had a problem playing back with Nero DVD. I don't know if I'm lucky but the process of backing up my DVDs is now a reliable and worthy one as there is no difference (to the naked eye) of quality between my originals and backups. I bless this ability seeing as I often insert one of my favourite comedy shows i.e. Red Dwarf or Family Guy or something I watch frequently and have it skip in my DVD player.
