DVD-RW writer only read CD's

Hi everyone, newbie here^^

I have recently brought a new pc, it came with a DVD-RW 16X HL-DT-ST DVDRRW GSA-H30L, which apprently is meant to write dvd’s too, but for some reason it only reads CD’s, and I can also only burn CD’s. The software I am using is Nero 7 premium and when i check the driver infomation in nero it says DMA off.
I dont know much about DVD writers, but it seems from what Iv read from forum this is important, any suggestion on how i can fix this problem?

Thanks

Hi impr3za
Weclome to CD Freaks
for the DMA issue click on the DMA RESET TOOL below in my signature download it and run it, that will set the DMA on your computer,you can run Nero infotool it will tell you what it supports as far as read and write and will also tell you what the firmware is for the burner, also you may want to check for a firmware update for your burner

Hi storm jumper thanks for your help
Iv done what you have suggested but when I run the software the following message appears.
"No ressettable ATA channels with windows drivers found. Nothing has changed"
I also forgot to mention that I am using windows Vista

here is the infomation from nero INFO tool

Nero InfoTool 3.06
