Drive appears to be okay... I backed up Crank and Babel with no problems (ANYDVD & CloneDVD worked like a charm). Checked Open Season and the disk appears to be free of any marks or blemishes, but once AnyDVD engages the DVD disappears from the drive. With ANYDVD shut down the disk appears and Ripit4Me gets to the second title chapter (with DVD Fab Decrypter) then ISO errors itself out. I'm at a total loss?!?
Download and install VSO Inspector and scan the disc for errors, it can do a surface scan and file test and if it finds any errors then you know that you got a bad source disc. Its a handy program to have, also you already got your answer on a bad source disc from when you tried to use RipIt4Me with the ISO errors.
