Sony dw-q28a (KFS1 firmware)

Hi Guys,

I have a sony dw-q28a (KFS1 firmware)
Will the firmware from http://codeguys.rpc1.org/firmwares.html#SOHW-1693S
work for me. The problem that I am having is bitsetting my DVD+R DL to DVD-ROM. It is greyed out using Nero CD-DVD speed.

Hope this make sense. Thanks for the help!
