hey bro! i think th problem is not with your xbox unit, pero baka dun sa nabili mong bala. if its pirated mejo may limitations or flaws sa burning or what, siguro, try other games and im sure may malalaro ka..pag mga 20 plus games na then puro ganun padin ang lumalabas, might as well check your unit/lens na
hope it helped kahit papano.
