On the other hand, last night i burned some TY cd-r, on 10x and scanned on my benq 1655 at 8x and 12x.
the first impression is that the burning improved, the PIF max is lower than before, about 12-16, no PIE of course, the score is 98, but the jitter started on the first burn at 16 and lowered to 11, and on the second burn started at 13 and lowered on 10.
Both cds were burned in imgburn at 10x, the lowest speed of the drive.
But, the device buffer fluctuated non-stop from 84%-92%-99%.
Before the firmware upgrade it remained constant at 100%, but the overall burn score was 95-96.
