For checking exactly what the Philips DVDR1648P, 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!
