For checking exactly what the PX-755A 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 Plextor DVDR- PX-755A drive. Using other drives, even another PX-755A, can produce totally different results. Be aware!

#2nd Test Disc - PISum8/PIF Comparison - 4X Reading speed

The trend lines produced by the 755A, to some degree follow the CATS trend lines but only in the case of PIF errors..
