My Xbox 360 kept giving me problems while i was playing some burned games, i.e. it froze up at random points, gave disc unreadable errors, etc. I took the DVD drive apart and cleaned it with rubbing alchohol 60% with a q-tip. Now, it just doesn't read my burned games anymore, i get open tray after it attempts to load the game. However, it reads my real games such as Elder Scrolls IV......just not anymore burned games, even those which never ever gave me problems. So uh....what the hell do I do now?!
