When doing PIE/PIF scans the drive always runs at the maximum speed (16x) so either qpxtool ignores the selected scan speed or it can't set it in the drive. Besides that the offered speeds seem a bit strange (2x, 5x, 8x and 12x) for a 16x drive anyway.

I can hear from the sound that the drive runs at full speed and scanning a complete DVD with 4,7 GB data just for PIE lasts about 5 minutes which translates to 15667 kB/s average (11x speed).
