BenQ DVD Writer DW 1620 PRO

Using WIN XP HOME (Dell Version)

Hi, I've been to hell and back trying to download the latest firmware
updates. I goofed and downloaded an older version by mistake. I clicked
FLASH instead of EXIT.

Then when I restarted, I got an error message that WIN XP could not
certify the hardware and warned that continuing could cause problems. I
was heartbroken!

So I went back in and downloaded another, hopefully later version of
firmware. Same error message. But this time when I restarted, I ignored
the error message, and continued to let WINXP load the drivers for the
BenQ.  Despite the dire warning, I no longer get an error message!

BUT, I do want to download the fastest FirmWare..but.I have no idea
which one it is. And getting help from BenQ, for an OEM/Bulk  burner is
out of the question.   Anybody with benQ DVD writers?

Thanks,

MIke
