Depends on the compression too. For example, Sorensen makes a really
small file but it does it by forcing the host computer to do a _lot_ of
calculation to get to any particular frame (the further past a keyframe
the more it has to calculate). You can sometimes get better response by
easing up on the compression and having a larger file with more key
frames, or if you know _exactly_ where you want to go in the DV, be sure
to have a keyframe (or two) right there.
