I bought benq OEM DVD burner(DW1620,G7C9 firmware).
I burned several DVD+R(Teon 8x and Memorex 8x) and scan the DVD+R for quality checking.
Yesterday,I flash the firmware to B7P9 and scan the DVD+R again to see if there are some difference.
I got very strange scan result.the scan under G7C9 firmware is very prefect and excellent quality.But the scan under B7P9 is not so good.pls check the picture I attached.
I am confused that the same DVD+R(burned using “G” firmware) is so different under diferent firmware.which result could I turst in?
