Well, I broke down and bought Quicktime Pro, followed the directions (linked to below) and fixed the sound sync problem. Now I’m trying to decide if I want to wait for iDVD 3 to arrive to do the chapter markers before burning the 10 DVDs I’m about to burn.
I spent a bunch of time on the labels, too. My color printer is hooked up to my PC, so I tried both CD Stomper and Easy CD Creator 4 label programs, and ended up liking the Easy CD one better. I grabbed a few background images from the web, scanned in some pictures, and had a pretty nice looking label and booklet in a couple of hours. I used the CD Stomper to put the labels on, and they look great.
