I won’t claim to be an expert in any way…but I’ve used this software for over a year with little problems. I did, however run into the same error your having when I recently changed burner drives.
I suspect its our drive firmware or dvd media causing the problem. I used memorex dvd media for six months or better with no trouble, but I’m told to try verbatium, which I’ll try this weekend.
I’ll let you know if I find a fix before one of the pros gets back to you. Several on this forum are very sharp and will help.
