Dual Layer with PNX7850E chipset

I have A NU DDW 82 DVD writer with Philips PNX7850E Chipset … Strange thing is that The BenQ DW822A DVD±R/RW having the same chipset announced that their drive will support DL at the 3rd quarter of 2004 with fw upgrade …NU may release similiar FW too?.. Maybe the Benq firmware work on NU od Modified firmware may work?
I just want to ask your ideas it just poped up in my mind…

Thnx for ur attention
