I have a Dell Optiplex GX270, with 512M Ram. It came with a CD ROM which I just replaced with a generic IDE DVD ROM. The CD ROM was working fine. My DVD ROM will not read any files except CDA, and it won't even play those. FIle Manager says it's working fine.
First I thought maybe my Codecs were bad, but if I plug an external, USB DVD reader in, it works fine and reads the same CDs that the internal one won't. I'm not even talking about DVD movies, but regular data files, like games (SIMS 2 to be specific).
Any help is greatly appreciated.
Thanks!
Chris
