Thanks to all! I am up an running! I noticed that a new firmware (BSQB) had just been released so following the link and instructions from zebadee for using Quikee's BQFlasher, I crossflashed from the OEM firmware to the lastest BenQ official firmware. The instructions were crystal clear and the whole process took less than 5 minutes, most of which was reboot time. I then test burned a dual layer +R disk with a movie with which I had previously had a very difficult time obtaining a quality burn with both a Lite-ON and NEC burners. Hands down, it was the best dual layer dvd that I have ever burned. PIE max 12/total 98k, PIF max 1/total 282. I now see why so many people think the DW1640 may be at the top of the short list of the best burners ever made.
Do I understand correctly, now that the drive is loaded with the Bxxx firmware, for future firmare upgrades, I simply have to run the Bxxx.exe excutable file?
Also, what is the convential wisdom for using Solid Burn with supported media? The default is not-activated. Should I be using Solid Burn anyway?
