I have had this problem also except I can't play anything not campaign not multiplayer and the 2nd disk won't even install anything. I even tried installing it from Xbox live and that didn't do anything. I can get to the main menu but I can't read anything because it can't spell like sometimes it will say apture he lag rather then capture the flag. I have the original white Xbox so I was wondering if it was that put I have seen other people who have been able to play it with the old xbox
