For checking exactly what the LiteOn SLW 831SX reports, we used three different media, burned with other recorders. The three media have been measured using 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 LiteOn SLW 831SX drive. Using other drives, even another SLW 831SX, can produce totally different results.

With DL media, the graph is totally different from the original CATS scan.
