I installed a used TDK 4X DVD Burned into a computer here at work. This replaced an older CD-RW Drive. I say used because I know that pre recoreded audio cds played just fine before.

Everything seemed to be going fine until the user tried to play a pre recorded audio cd in the drive. Data CDs come up just fine as do burned audio cds.

I have replaced the ide cable, updated the firmware on the drive and changed all bios drive settings to AUTO.

Any ideas??
