I agree, probably a hardware fault.
The real purpose of my reply is to plug CDBurnerXP, a free program which I now much prefer to the Nero bloatware. I don't want my burning program to manage my music, transcode to VCD and make coffee. I want to burn and create ISOs and burn arbitrary files.

Another vote for CDBurnerXP and against Nero. The next problem is How To Remove All Traces of Nero. Googling suggests it isn't as easy as you think.
Not only is it bloatware, but also sticks it's tentacles deep in your system. Is there a -ware expression for that?
So, my plug is for
Revo Uninstaller (which should be used in conjunction with other strategies to get rid of Nero).
