very recently, my xbox has been incorrect in reading the games i try to play. at start up, it will say the disc is a multimedia disc or a dvd, even though its a game in the tray. opening and closing it once fixes the issue, but i was wondering if its a sign of bad things to come considering ive had freezes. mostly the freezes have been with battlefield 3 and im sure im not the only one with that game, but with other games too (moh: warfigher and farcry 3). what could this be, and how would i fix it if it becomes worse? any help is appreciated, thanks in advance.
