I just purchased the OEM version of the NEC 2500A DVD-RW drive, and I’ve been having nothing but problems ever since. I have:
[li]Windows XP Home
[/li][li]DVD X Copy Express
[/li][li]Have no idea what DMA is and how I can enable/disable it
[/li][li]Ritek 4X DVD-R’s
The first problem is that sometimes my system won’t even detect that the drive is there when I look in my computer. When I try to add the drive in add hardware, it seems to work then.
The biggest problem, however, is that I can’t get successful backups of my dvds. Only one has worked (Training Day). For other dvds, it won’t even begin ripping, and DVD X Copy Express gives me errors such as “can’t read library” or similar. With another dvd (Being John Malkovich), I was able to rip and burn the dvd, but the backup just won’t play, even on my friends dvd player which works fine. Another dvd (Election) just won’t play at all in my drive, but works in my friends dvd player and my own dvd player connected to my TV.
The drive was screwy to begin with. I tried downloading new firmware, and a firmware flasher from http://tdb.rpc1.org/ (dangerous brothers website), and used those, and nothing seemed to work.
I know my problem here is really broad, but can anyone suggest anything or help? It would be greatly appreciated.
