Thanks Boss, that was soothing and stimulating at the same time.
Connie, my computer at home does that too (slower DSL than at the shop.) It must be that the video download speed is slower than the video play. I agree that it's annoying so what I do is let it download (play) for a few minutes then begin the video from the beginning. That way you don't get constant "jerking." Try it, this video is worth seeing again.
