I am having problems with my burner making DVD-R discs, has anyone else had this problem? DVD+R's work fine, the drive just doesn't burn to DVD-R's anymore and I get an error when I use DVDA 3. I have burnt DVD-R's before, but with an earlier version of firmware.
Here is some data on various media and it's compatibility with that burner based upon user experience. In terms of the firmware, have you tried firmware JY03?
