I'm having a problem with my backups it shows up on the right hand corner of the xbox that theres a game but when i play it it just freezes i tried nero and img burn on maxwell dvd-r.
If you don't have room on ur HDD, then burn at a lower speed. I use Memorex (yeah I know horrible), but so far I haven't had one bad burn (I burn at x4 with EVERYTHING). Try burning at a slower speed, and if that doesn't work, experience with some new media.
Ya im not sure what it is because I always burn at low speeds and I've used this media successfully before,I guess maybe i just got lucky before time to upgrade on media.The iso's should be good because i ripped them i didnt download them.
Qwix makes bad xiso's a lot of the time... try this tool instead http://downloads.xbox360-tribe.org/index.php?act=view&id=794
