I started backing up some Xbox 360 games, but I've only managed to burn 2 discs succesfully out of 7 so far. One written at 4x, the other at 6x. The other discs have been coasters mostly, with various error messages showing in ImgBurn.
I've included the scans of the 2 succesful burns, and one I did using CodeKing's CFW (the worst one). I'm using firmware 9L09N.
Does anyone know what's going on here? If I understand correctly, then according to this link my problem could be due to some sort of new manufacturing method?
Originally I wanted to burn these discs with my BenQ DW1620, but they are not supported. What can I do here? Buy a new drive? Any suggestions?
