Okay I tried all the adjustments I can and only mw3 says play game. All other 360 games say play DVD. Does this mean it's the key? I called the original owners and they wont answer.
Is this after tweaking the DVD pot? MW3 is a pretty new game, which means it may be a much cleaner disc than your other games (free from scratches and smudges, etc.) It will be easier for the laser to read than your other games. If the laser can only read that game, you might want to tweak it a tiny bit more so that it's at its prime. Otherwise a new laser may be in your future.
And no, if it will read that game, I think a key problem can be ruled out.....probably.
