HL-DT-ST DVDRRW GCA-4164b not detecting correct DVD+R speed

I have the above Hitachi\LG drive in my HP PC and it is at the latest firmware level - H10.
Frow what I read on this wonderful site is that the firmware is not correctly set for the DVD’s I am using.
It detects Verbatim 16x DVD+R ok but my Philips DVD+R 16x it only lets me write at 4x.

Help please as HP support are useless.

Cheers,
Dave

Hi and Welcome!

the Philips branded media (this comes from different manufacturers) you are using is not mentioned in the “table of supported media” that is part of the firmware. If there is no newer firmware for your drive, then there is nothing you can do about that. So stick with Verbatims in future.
