DW 1640 writing speed problem help

Hi Newbie here,

I just bought benq dw 1640 and updated fw to BSOB.
My problem lies within burning speed. I’m using OPTODISCOR8 right now. I know its not the best product. Well the problem is some of the discs are burning aprox. 8 min (so im assuming writing speed is near 8x) and other are taking like 12-14 minutes to burn (which seems that speed is slightly over 4x).
While testing these DVD everything seemed fine.
is there enyone with the same problem? Is it 1640’s fault or maybe media fault. Appreciate any solution.

Hi :slight_smile:

thanks
