Same Issue here. I bought two games with my "Day One" system Madden 25, and COD Ghosts. Madden would play just fine, however; couldn't get COD to even show up in the home menu to load. I called XBox support and the guy right away asked me what the bottom side of the COD disk looked like. I said good, because it had just came out of the box cover for the first time. But when I compared it to the Madden Disk I could see that it was damaged It appears to be a manufacturing issue with the disk, almost like it got too hot when it was being made. The Madden Disk was for the most part, a consistent color but the COD disk had a rainbow like sheen coloring to the back side. I guess that was the reasoning why the laser cant read it. Like I said the COD disk literary had just been opened, brand new; out of the cover. I had bought it from Amazon and they are sending me a new one out today.
