thanks guys for all the useful posts!
I am using the maxell 8x dvd-r RG 03's
I heard somewhere that setting the bitsetting to dvd-rom for any xbox disc helps, + or - . I may have been misled, but it may be worth a shot. Also what does anyone who has this drive think about the KY04(newest) firmware? I updated my drive using it, and i havent tried burning with it yet(after upgrade).
Also: Is there no possible way to burn slower than 4x? possibly 2x? Because my games seemed to work everytime with that speed using a tdk external dvd recorder.
