Recently I had burned the AI Revision Mappack to a disc and was playing that on my xbox, and then I erased that disc and put on the Killtrocity Mappack, then I wanted to play it today, and my xbox wasn't reading the disc, it said it was empty, so I tried a actual game, not a burnt disc, and it played, then later today, I tried to play the game again, and it took real long to read it, and it recognized it as a video and didn't play/launch. So what happened to my xbox, cause now I cant play games.
