The firmware page suggests that your drive in a BenQ 822 drive, based on the current B3BC firmware. Since your firmware is a bit old, you might want to upgrade it.
If I were you I'd avoid the very latest B3KC; it's the one that supports +R, -R, and double-layer discs in the same firmware. It would seem that there wasn't enough room in the firmware to properly support all of this, so it's my feeling that the firmware was compromised to accomodate it.
Firmware B3IC is an excellent choice for +R and some -R media. B3JCY is a bit different in that it allows you to switch between two modes "+R and -R" or "+R and double layer" mode of operation. I've found the "+R and double layer mode" to provide the best +R burns for me - even thought I don't burn any double layer media.
In my opinion -R support is poor in the 822 and should generally be avoided.
