The other night I was playing Call of Duty2 and when I attempted to exit the game it froze and I had to power off the unit. Last night I attempted to play game again, I power up the unit, place game in drive, it says reading but the screen stays blank and game does not play. If I insert older game (Halo2) it reads and plays game, same with Music CD or DVD. My question is: Do you guys think issue with game or do I have issue with XBOX360 unit? As luck would have it I am still in the 30day return policy for the xbox360. Any thoughts or comments is appreciated.
