Ya this is were it gets tricky, why is it happening it one thing but why is it happening to 2 different xbox's??...the cd worked fine then out of the blue they start this.....heres the only other thing i can think of but i doubt it matters, the cd's that came with the xbox's, we switched them, he has the cd that came with mine and i have his, its hard to explain why we did this, it was just eaiser when i modded his xbox to trade him the one i already modded, anyways would a cd that came with it have any kinda relation to the original xbox?
