I just purchased Bioshock Infinite today and when i try to play or install it, it says the disk is unreadable. I got another disk today and it said the same thing. Every other game and movie works on my xbox without any trouble. I have cleaned my cache multiple times, restarted, uninstalled title updates, reinstalled them, checked for any scratch in both video games and none of this has seemed to work. I really don't want to buy a new xbox for one game.
