Not sure what TSR means here (As I read it as Terminate Stay Resident)....anywhoo
check your parental controll settings. That was what was keeping my friends xbox from loading Burnout Revenge, and a few other games. It would spit him back to dash, he had it set up to Adults Only, but I'm guessing Burnout Revenge is Rating Pending, because when I had him set it to that, it started to load up (as well as some other games that "weren't working").
