Hello. I have a DELL Dimension E510. My OS is Win XP Media Center Edition Version 2002 SP2. My CD/DVD drive is listed under device manager as HL-DT-ST DVD+-RW GWA41G4B. I just recently purchased my first PC-DVD game: Call of Duty 4. When I put the game disc in the drive, nothing happens except that the drive makes a series of grumbling and whining sounds as though it's trying to read the disc and then quits. I tested the drive by trying both a music cd and a dvd movie. Both of these worked without a hitch. I then tested the game disc by placing it in my home entertainment system dvd player (non-pc). The dvd player recognized the disc and displayed the folders that are present on it. I went to Dell's driver support page and installed an optional update for my cd/dvd driver. No luck. Any ideas?
