When i put in either of the multiplayer or singleplayer discs, i get to the screen where you have to press start. When i do, the screen goes black and i hear the dashboard open up. Then i open the disc tray and i see a flash of an error saying that the disc is unreadable. All of my other games don't do this and it is with both Battlefield discs, which are both only 1 1/2 months old and have no scratches. Any ideas on what to do? And dont say get a ps3, i have an xbox because i have more friends on there. Any help is appreciated!
