about a month ago I purchased the Sony DRU-700A, and since then I have backed up about 50 movies without any problems. I use DVD Decrypter to rip the movie, then DVD Shrink to encode, then I use Nero Smart Start, and burn the files. Yesterday, when trying to back up one of my Family Guy seasons, I did the same thing I always do, and the burn was successful. However, when I put the dvd into my dvd player, it wouldn't play it for some reason. Then I put the disk into my dvd drive, and I clicked on My Coomputer. When I went in, the DVD Drive had changed from DVD-RW Drive to CD-Drive, and it wouldn't detect my disk. Then I tried to rip it again with dvd Decrypter, but decrypter couldn't detect the disk either. For some reason the disk will play in Nero Showtime even though it doesn't say there is a dvd disk when looking at the drive in My Computer. The only thing I could think of that could be wrong was that I upgraded my firmware or whatever to the latest version, but the problems were occuring before then as well. Any help would be greatly appreciated. I am using just blank generic DVD+R, and I have a P4 2.4 ghz processor, with 640mb of DDR RAM. Again, thanks in advance for any help.
