Thanks indeed for this info.  I'll take a closer look at my original frames,
although I'm 99% sure that the original un-blurred animation itself doesn't
include duplicate frames. (The scene's animation code--and my 'post'-blurring
code, averaging each 15 frame batch--are both 'clean' AFAIK, and wouldn't have
produced a duplicate frame, anywhere in the chain.)  It's definitely a strange
situation.

Before posting my animation file, I actually went through two complete attempts
at encoding the 'blurred' animation in monkeyjam (using the xvid MPEG codec,
BTW), and both times, the same little stutter showed up when I viewed it in
W.M.P. I haven't seen such a glitch before, in my other similarly-made
animations.

Time to do some detective work!
