BenQ 1625 wont read any DVD-R media

I have a HP 640i lightscribe, which I successfully flashed to a BenQ 1625…running BBIA firmware.

First stack of TDK media was fine…bought the exact same kind, and it wont read the disc at all. Bought HP dvd-r, same thing. It reads regular or burned dvds, cd-r, everything but dvd-r.

At this point I’d just like to flash it back to the HP if there’s a way. I’ve tried several firmware’s, settings, etc. I’ve seen this problem around, but no one seems to have a real solution…I’ve tried everything I can. At this point just want to turn it back to the HP so I can try their firmware.

Thanks in advance.
