What exactly did the error say? What kind of disc are you burning to?
I get a different one every time try it. I get one at 99% that says it can’t finish the disk. I am using blank DVD’s I bought a while back, can’t remember what type it was. When I take the disk out of my computer’s tray after attempting to burn, it is obvious on the back that there is something written to it, but when I insert it into my Xbox it get something along the lines of “This disk can not be played”.
