Does this mean: Nothing wrong with CloneCD, just the burner ignores the command?
I see the byte/sec and the total time to burn the while CD.
Back in the 90's the Redbook standard recommended to burn music CDs at 1x speed. However, back then the writers were only capable of burning 1x/2x and had no burn proof functions.
The firmware of modern drives doesn't allow such slow speeds anymore.
