I recently got two BenQ DW1620. One is Pro, the other is not (but I think the Pro only came with a better FW, isn't it?).
I have the following problems (tested with TDB's B7W9 and B7V9 firmwares):
Drive1) Will burn MCC RG03 (Verbatim -R 16X) Media actual 8X when I asked for 16X, but even worse, every DVD I try to read (CD-DVD Speed or Alcohol ISO Making) will report 4.38 GB independantly from the actual capacity of the disc. While read testing the drive in CD-DVD Speed it will give an error when it starts to read the blank sectors...
While testing reads will sometimes be 8X limited, sometimes not... even with the same disc!!
Drive2) Works flawlessly (from what I've seen), it burns my Verbatims in less than 6 minutes (+-) but it won't ever read a DVD-R or DVD9 at more than 8X!!!
What could be the issue?
Thanks in advance
