The DVD RW drive I originally had with the computer stopped working, and so I took the lid off and the two screws came out then, nothing went inside the computer.
I brought a new drive, assuming this was the only problem and this is a HL Storage CD-RW/DVD-ROM drive. Its the only disk drive I have on the comuter, hence the problem =S
This drive will play CDs and it will play the audio on DVDs when it plays through Media Player but when I play it through InterVideo WinDVD 8 that message comes up. The device is connected to the motherboard through a ide cable. There weren't any device drivers with the drive, it came by itself.
Hope this information helps!
