Unreal Tournament

[johnny utah]

Ok, i burned a copy of unreal tournament a while back, using my friends game that he bought. But now, i wanna make another copy from the copy, but every program i tried can't read it and i dont know wth is going on, my burner could read the original but it can't the recorded? i have a sony145 and the burned copy runs just fine. i can't read the original of age of empire 2 : the conquerors either. tried reading with my dvd/rom also but that give me the same problem, with nero it stays at 0%, blind read dosn't even start to read it, and wincd gives me errors too. don't anyone have this same problem?
