Problems with GMA-4080N

Hi all

First sry my english…
I got a problem with my DVD-RAM drive. A few months ago I purchased a GMA-4080N DVD+R DL. It was described as an DVD±R/RW and +R DL drive.

My problem is, that it doesnt recognize any +R/RW media and any +R DL media. I tryed more brands. Reading and copying of the -R/RW media is OK, but sometimes i can burn media described as 8x only with 2x.

A friend of mine told me, that maybe would help a change of the firmware. Now it is working with a 0F37 firmware.

Can anybody help me with my problem?

THX to all

Just use recommended media. eg. Verbatim and TY.
