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

The error line trend follows a completely different pattern to the CATS scans. Once again, the actual speed was rather low, 0.5X~1X.
