been doing a couple of games for the kids for the xbox i have done them before a while ago but it seems this time they are failing me i dont know why

they are mirror DL disks the guy in the shop has had no problems with them, the file i am using has been verified by other d/loaders as good i am using imgburn and have tried clonecd but for some reason it wont work

i have ran it through abgx360 or whatever its called and it seems fine (even though i dont really know what im looking for) anyways any tips for imgburn would be great thanks
