This drive does not work! Tried +10 different media with 4x, 8x, 16xSpeeds and quality brands (Sony, Verbatim. etc.), also tried writing at 2x to a 16x media... It all seems great until you try to play the DVD on a player. We have tried every disc on +30 players with no success. NONE of the DVDs worked on any DVD Player. Bitsetting, Booktype... nothing works. It doesn't even properly read the data discs written by itself! I have also tried testing it on a different PC but the results were even worse. I have been using Pioneer DVR-109 since last year and even at 16x on unbranded media it never fails!

It is a BenQ 1620 (Pro) OEM and can be flashed to BenQ's firmwares with
WinDWFlash and there'll be no difference from BenQ 1620 Pro. Since firmware
version B7P9 (BenQ) / G7P9 (OEM), 2.4x DL DVD+R feature is upgraded to 4x.
If you worry about warranty, you can flash back to G7*9, the OEM firmwares anytime.
Also you will then be able to use these useful BenQ-exclusive utilities:
- Qscan 1.0 (scan the disc quality before burning, deciding which speed to
- Booktype Management 8.4 (for bitsetting DVD+R/RW/DL but the default
settings should already be set to "DVD-ROM" and
- Qvideo 2.0 (capture and burn in real-time directly to CD/DVD)
ALL can be downloaded on the Internet for free.

Great here too! Easy to install, but the in-box IDE cable was pretty crappy, IMO.
Burns Ridata 8x at 12x with no problems. No coasters after burning a 10-pack of movie and data backups.
Fast and real quiet. Bought in Korea for about U.S.$80.

No problems so far. I have burnt 2 printable Ridata 4x disks and no coaster.
The drive is quiet and reads quite fast (esp. compared to my DRU500A!!!). It installed with no problem.
