My xbox 360 is a modded 1. It plays burned games tht r found in our market. Bt recently i bought Batman arkham asylym & dirt 2. But these games are not running in my 360. When i entr the disk, it says play dvd & then opens up a xbox 360 logo screen. then whn i press any button in my controller, it opens up the dvd media menu. What can i do? Is it a dvd prblem? I called the shop & he told me that my software needs to b updated.i knw its nt the drive cos all my other games are running.
