I am unable to burn at 16x.
This only happens in nero. All other programs burn fine at 16x.It starts burning then errors out at 5%. I am using nero 7, 5, 9, 0.
Try new version 188.8.131.52!
You might want to post your HeroHistory log and take out the serial numbers and edit it to the last couple of burn attempts.
Have you tried different media and allow it to do a speed check? Some types of burns should not be done at a fast rate, even if the burner allows it.
Why don't you just update to 184.108.40.206 the latest version.
