Any difference between the BenQ 1620 & Pacific Digital Mach 16?

I picked up a Pacific Digital Mach 16 which is a re bagged BenQ 1620. The price was right on the pacific Digital drive Should I keep firmware or flash it to the latest BenQ firmware I believe it has the BenQ firmware… Also how is this drive for backing up dvd movies and reading copy protected dvd’s

I’m guessing you got it at Staples for a good price. In any event, mine was a BenQ 1620. I flashed it to G7P9. It burns flawlessly. You most likely have the same drive.
Visit the BenQ site, not the PD site for updates.
