For checking exactly what the SOHW-1673S 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 4X reading speed.

Please note that the posted results are only valid for the specific tested LiteON SOHW-1673S drive. Using other drives, even another SOHW-1673S, can produce totally different results. Be aware!

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

In this case, the graph patterns differ from the CATS error line pattern.
