Sorry if iam missing anything am new to this...

I'm a rookie at this stuff, but I have modded the firmware of 9 or 10 different 360s. Like wuzuplj wrote, Is your Xbox firmware modded? If so, which DVD Drive does your Xbox have? Which firmware version did you use? Which Brand discs did you burn the backups on? I have had 100% success playing backups on all ytpes of DVD Drives, except on TS-H943 Drives. I used the same procedures as the other 8 drives, but they would not play Backups at all. I never tried burning on Verbatim discs, but that could have been my problem, as well as yours.
