I'm goin to start to work on this, to list bad burns etc by finding them all over the forum... I hope people can discuss solutions or trouble shoot. This might prevent others from screwing up discs.
So far problem I have had 3 coasters, I think memorex CMC MAG E01 and possibly all CMC MAG E01 cannot burn at 8x with 1633s.
Burner: 1633@1653 CS0M and CS0P
Burn Speed: 8x
However successful at 4x.
