There's newer firmware available for your burner (remove any disc and close the tray before updating then reboot after it's finished) but use your WinXP if you're going to update.
I updated the DVD driver to 1.05 FW, and still have the problem.
Also I have an ASUS P5P800 motherboard. I looked for chipset drivers, and they didnt have any.
Do you have any other suggestions?
