The "interlaced" flag TO -vf scale.  Presumably, the video is
interlaced, and scaling like normal (progressive) video will just
destroy the picture.

But yes, you'll want ildct and ilme as well.

Like any math problem... 25 just doesn't go into 30.

Professionally converted videos commonly ghost/motion-blur the fields to
smooth the motion of the video, but the quality suffers, and I don't
believe mencoder has any way of doing that, though I can imagine
modifying something like tinterlaced (and using pp=lb) could make that
work.
