I set my little vid thumbnails in the menu to be Animated. I have about say 5 vid thumbnails, and when I view in preview they look a little choppy, and then after a time they seem like they go in normal motion of animated. Is that normal, or is it gonna look that way when burned on disc? Could the issue be that there are too many vid thumbnails? I've done this before long ago with my old computer and didn't have the issue. And on my new computer I have the I5 Processor with 6.0 Ram, 600 Watt power surge, and very strong HD graphics card.
