New bulk fw G7V9 and 4x dvd+r DL burning

is it possible to burn dvd+r Dl @4x with this new bulk firmware G7V9?

this fw can be found here:

I checked this fw with the msce-tool and it shows the writing speed for verbatim DVD+R DL (double layer) @ 4x

>>> dvd+rdl mkm 001 4x, 2.4x <<<

has someone tested verbatim dual layer with this or another bulk fw?
