Write dvd-r at 2x with dw822a?

Is there a way to write dvd-r at 2x? Will firmware B3BC work? Thanks.

Upgrade to the newest firmware and chose 2x burn under NERO.

Running Nero 6, and B3IC firmware (nothing newer so far), and nero only offers me two options when I try to burn DVD-R media. The only speed options offered are 2.4x (noted as invalid in DVD Identifier for -R media), and 4x.

No success getting 1x or 2x media to even be recognized except for reading on already burned discs.

the Benq drives do not support 2x so all 2x discs (even -RW) will be written at 2.4x
