Hi does anyone know the answer to this, I have a Xbox 360 thats been flashed, what version I don't know. I play all my games on line with no problems, apart from Battle field 2. This game I am addicted to online, my problem is after I have played it for a while online the xbox says the disc is dirty it needs cleaning, even when I have taken it out and cleaned it I sometimes get the message. If I re-burn the same copy its fine for a while then it tells me to clean the disc. What I don't understand is that if I play the game off line no probs. Its only this game I have problems with, I use the same dual layer discs on all my backups so I know its not the discs, and the laser of the Xbox 360 must be ok because it plays fine with all my other games.
