I don't know, but Nero is a good program, but it fails to burn my stuff with my LGs. I use Roxio and they all burn correctly. Like, the Vista 5840 DVD, Alcohol 120% can't burn properly. The first, in my PC, it won't work, but my mother's will. The second and third, bad. The last was burned with Roxio. Right off the bat, one hour later, I run the Standalone Vista. Tweaked that it looks the same as XP.
