Okay, I have Crackdown, and I burned it to a disc. I've been playing it for hours today, and even played Co-op online. When I was online though, it said that the connection was lost, and it kicked me from the game. I then got a White Screen, so I went to the Dashboard. Then it said that the disc was an "unreadable disc". So I restarted my 360, and booted the game, and it said again that it was unreadable, and that I should clean it. I rubbed it with a cloth, and put it back in the 360, and it loaded to the White Screen again. Does anyone know why this is happening? Thanks!!!
