text: I use DVD Shrink frequently and I have often come up against this error. I don't know exactly what it means, but I think it's about the drive, not the dvd. I have two drives in my system, and if one doesn't work I try the other one. I have yet to run into a dvd that won't rip from either drive. I would suggest using a second dvd drive or a different computer altogether.\n\nP.S. I believe that DVD+-RW drives don't like dvd shrink and generate that error. A standard DVD-ROM tends to work better\n\nP.P.S. DVD Shrink can import already ripped dvds. I keep a copy of DVD Decrypter around in case.
