How do you control this?  All I've noticed in the mythtv
configuration (on, IIRC, mythfrontend) is 'deinterlace video on/off',
nothing to control how it's deinterlaced.

My particular situation is that I sometimes get double-images on my
TV which make it feel choppy.  Pausing and going through it frame-by-
frame, I'll see that the image actually is doubled, with a (e.g.) 1/3
transparent copy of something in the old position and a 2/3
transparent copy of it in the new position.  (This is most clearly
visible on animated programs, of course.)  The odd thing is that
watching avi or mpg files not created by mythtv on the TV looks fine
and watching mythtv's recordings on a remote front end attached to an
LCD monitor also looks fine.  It's only the combination of a myth
recording and the TV display that has this problem.  I've tried
setting the frontend on the TV to both deinterlace and not
deinterlace, but it has not had any readily-visible effect on this
problem either way.

The freedoms that we enjoy presently are the most important victories of the
White Hats over the past several millennia, and it is vitally important that
we don't give them up now, only because we are frightened.
