Hi, Has anyone ever heard of this drive stopping to recognize DVDs? The drive has worked fine for several months, but now will not recognize DVDs. I can still read and burn CDs, and my system shows the drive to be functioning properly. The region code is correct, and becasue I have XP, I don't think it is a driver problem. When I put a DVD in and look at the drive with windows explorer, the drive shows "no disk". Any suggestions would be greatly appreciated Thanks!!! Jim
