I have an Emprex AW-G170-A-B2 branded Sony. It shows up in my system as a Sony AW-G170A with firmware 1.71. Problem is when i burn, it burns at x16 which doen’t give me that great of a burn. I would like to get it down to at least x8 if not x4. I use Tayio Yudens T02 x8 burn speed. Is there anything i can do? New firmware??
