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

#1st Test Disc - PISum8/PIF Comparison - 8X Reading speed

From the above graphs, we can see that for the PI Sum 8 Average, the trend is similar but the values are very different. With the PIF average, the LiteOn drive is very close to the CATS scans.
