ive retried burning several different games, using several different tutorials and programs and still nothing seems to work...not sure what im doing wrong here

usually i just got games from the person who flashed my xbox, i dont know much about his burning process, just that he rips off the 360 game himself instead of downloading the ISO's online....dont know if that makes a big difference. ive tried to burn different games and they all burn fine but when i attempt to play them in my 360 it will attempt to read for a while until it ejects the game.

using Verbatim 8.5gb 2.4x dual layer i can burn the iso to the disc fine but when i attempt to play it in my xbox it wont work (my xbox 360 is flashed and has played backed up games before) just wondering if anyone could tell me what im doing wrong. here's the log: I 15:42:15 ImgBurn Version 2.5.0.0 started!
