Try Sony's line that I've mentioned many times. Motion blur is one of
the problems you run into that can be caused by different things.
Trying to avoid getting super technical about video stuff in this
newsgroup. Google topics like 3:2 pulldown, interlacing, and video
fields. Pretty good illustration, many others out there:

Causes of choppy playback and motion blur are really two different
things. Bluring can happen if the action gets too fast. This can be
reduced by higher bitrates and by applying various filter methods like
Gaussian blur through one of several methods like interpolate fields,
or blending fields. Read up on Interlacing first to understand better.
It can make things worse if field order isn't right. For NTSC specs
Field order needs to lower field first. Pixel Aspect Ratio also plays
a part in how sharp the image is. For DVD it should be .9091.
