For checking exactly what the Philips DVDR1648P reports, we used four 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 Philips DVDR1648P drive. Using other drives, even another Philips DVDR1648P, can produce totally different results. Be aware!

As you can easily see in the graphs above, the error line trend follows the same pattern as the CATS system's scans, but error values are different. Scanning is supposed to be at 4X but the actual speed was only 0.5X~1X.
