Sony dvd+-rw dw-d56a

does anyone have problem burning with this dvd writer? i could only burn dvd at 4x not 8x. when i contacted dell about the firmware, they said that the one that i have, “pds3 double layer”, is up to date and from other forum, it seems to be the updated firmware also. is this a sony writer problem and should i contacted dell on exchanging the dvd burner on my laptop?

the media supports 8x? if it does then your burners firmware probably dont like it much
try another brand

i used an imation and philips 8x dvd disk and got the same result, so its not the dvd brand since philips is one of the best out there. i still can’t figure out why it could only burn at 4x and not 8x.
