For checking exactly what the BenQ DW1655 reports, we used three different media, burned with other recorders. The three media have been measured with the well known AudioDev SA300 DVD CATS system at 1X.

The drive is capable of reporting PI/PIF errors, so we will compare those measurements at 8X reading speed.

Please note that the posted results are only valid for the specific tested BenQ DW1655 drive. Using other drives, even another DW1655, can produce totally different results. Be aware!
