                  Hmmmm, I haven't noticed the jerkiness.   Seemed to save some bits
                  but perhaps not as many as it could.

I never noticed before, but on a high-motion scene played back on the
TV the slow-motion effect was very prominent.

And what I meant to say was, not using -I for interlaced inputs
doesn't save (m)any bits versus using -I.  In all my tests
yuvmedianfilter (used correctly or not) saves a lot more bits than
yuvdenoise.  Direct comparison shows why - yuvmedianfilter really
softens the picture a lot.  Median filtering in general is great for
noise distributions with long tails (non-gaussian, impulsive noise)
since it can exclude large outliers rather than averaging them in like
linear filtering, but the flip-side seems to be that edge detail gets
obliterated.  There are lots of different median-filtering schemes out
there that are probably better than this simple one, but it's not
really my area.
