I spoke to Benq technical support. They have no release date on when new firmware will be available for this drive. The issue involves only being able to burn verbatim dvd +r dl at 2.4x instead of 6x or 8x. They are not good in response to emails, but it took me 25 minutes to get tech support. They say to adjust settings in the program. However, I feel it a firmware update issue. I am using firmware version BCAB which is retail. I certainly hope they resolve the issue soon as many complaints i am sure are felt throughout the forum in regards to slow burning of discs that can be accomplished in 20 minutes instead of 45 minutes.
My system runs a Celeron 2.4 GHz, 128 mb NVIDIA graphics card, 1 GB of RAM, 3 HDD, benq dw 1655 and dvd rom 16x
