Ncaa Football 2004

i'm having a problem with this game, i've patched the default.xbe file with isocraxtion just like i have done many times before but then when i burnt it to a dvd-r and stuck it in the xbox, i get a disc is dirty or damged error from the game, not the xbox unrecognized disc error, but the actual in the game disc is dirty error. so then i tried burning it on a dvd+rw and i get the same error. Does anyone know what's goin on here? Thanks
