According to the Canadian BenQ site, the stock firmware only supports 4x DVD-R writing.
HOWEVER, here’s what readme for the B3HC firmware update says:
> Release Reasons:
>
> 1. Support 8x DVD-R writing (TAIYO YUDEN, Maxell & Ritek-G06 8x DVD-R media)
> 2. Improve the writing quality of Longten 8x DVD+R media
In my personal experience with my 822A, the drive is extremely picky when it comes to DVD-R media, so you should buy just a small sample (one or two discs) to test first, before buying a whole spindle. By picky, I don’t mean it just burns at a slower speed (as many drives do), I mean that the media it doesn’t like, it will just spit out or coaster on the lead-out. It has no such compatibility issues with DVD+R media. It seems to be able to digest just about any brand of DVD+R I feed it.
From my own experiences (apparently, others have different experiences), I’d suggest you skip over this drive. If you want a BenQ, go with the 1620, which is supposed to have fewer compatibility bugs, or go with another brand.
