I've got 2 DVD burners which are compatible with the BurnerMax payload tool, any time I burn a XGD3 game I have trouble getting the xbox to even recognise the disc as a game, it usually says that it is a mixed media disc but on the odd occaision that it does boot the game will play for x amount of time then I'll either get 1 of 2 errors which are 'Can not authorise disc' or 'Disc dirty'. I'm using Singapore Verbatims and I'm burning at 4x which has worked for me for years. I don't have any problems with any other games, only xdg3 games give me this trouble.
