Roxio is indeed a powerfull program. A bit too powerfull for my tastes. I had about %20 burn failure with it back in 2001-2002. Granted it will do things Nero could only dream of, it still hogs requests and bullies other programs. If you want to capture stills from dvd, Nero premium "showtime" dvd player will capture to your hearts content.
I was just throwing out my .02 to NotJustAnotherPrettyFace. I've seen a lot ot posts in the past mention Nero. Never used it myself but it looks like a nice arrow in the quiver. I'll have to look into Nero's details. BTW, I use a Mac G4 dual. I do a lot of graphics work. I don't have anything against PC's. Just a personal preference.
