It's probably my xbox having an issue but I just wanted to get some peoples' opinions on this - a few months ago, I used to play MW2 all the time, and then the disc stopped working. I haven't been able to play it since. Just recently I noticed that there is a circular scratch around the center of the disc. I compared this scratch with my black ops, cod4, and other discs and they all have this circular scratch around the center. It's strange though because, other than MW2, my discs load fine. I can't get on multiplayer on MW2 but I can get on multiplayer on BO and MW.
Is this a problem with my xbox? Should I send it in to get fixed?
