My 360 wont read the disks?

Well your DVD Drive in your Xbox might be broken/messed up. My cousin has similar problems whenever he tries to play games. For example... He got Halo Wars just yesterday and wanted to install it to his Xbox, the game is obviously brand new. About 40% into the install, his Xbox tells him that the disk is unreadable. "The disc has also become unreadable" has also occured while playing Fallout 3. His Xbox won't even read his Unreal Tournament 3 game. As far as something to do about it, you might want to give 18004MYXBOX a call. Hope this helps!
