I just received this burner as replacement for a defective DRU-810A. I’ve burned about 10 DVDs till now with perfect results. But I notice in every burn that the buffer’s device oscillated between 9%, 84%, 92% and 97%; and in spite of this behavior, the DVD burned well.
The firmware of the DRU-820A is 1.0b, so i don’t know if it’s recommendable to update the firmware.
Thanks in advance for you time and Happy new year!!
