Recently, several movies don't read using dvd decrypter, both with and without anydvd running in the backbround and using DVD Xcopy Platinum both with and without anydvd running in the background. Any clues, as this has not ever happened before. I keep my lense clean, the drive reads 99% of what I feed it in original DVDs. It's a Liteonit 4X burner and has copied well over 900 movies. It don't act like it's going out and still copies most movies like AVP,etc. Any guesses? The drive makes a chunk chunk sound like its having trouble reading where the data starts(my guess) when it won't read.
