I use the same program. Just started to use it recently myself. If by crappy/scrambly you mean really choppy and not in sync with the original, then I have the same problem. Go to Video Options and play around with the numbers, but unless it's just me... I doubt you or anyone would be able to get flawlessly smooth transitions using that program any time soon. If it's claymation or something like it, I guess it's passable since it's slightly choppy to begin with anyway. I got the footage of the T-Rex's foot in the mud from the trailer not the link you provided, by the way.
