New one on me....had COD2 in the machine, turned it on and then hit eject. Put Burnout Revenge in the tray and message came up saying something alone the lines of "to play this disc place it in an xbox360"....what the hell? What machine did it think it was? Went back to blades and hit play, same message came up. Turned unit off and restarted and the game then started fine....bizzaro
