I have the burner : PHILIPS DVD+-RW DVD8631 and the firmware revision : CD21.
Do you think there is a new firmware revision? Because I have some problem to burn dvd.
I used dvd that the media code for Maxell DVD-R 8X is RITEKG05. I was able to burn on these medias (I did maybe 27 of them). They all come from Taiwan. But the last one I tried to burn was Three's Company. It's episodes. The burning didn't complete. It was frozen. I had to reboot.
