hmmm, ok. that's right, i completely oversaw this (i will check again
your suggestion about skipped frames)

still, i guess the movement will be hardly smooth for this sequence,
even if we follow all flags and don't skip anything. there is probably
motion on consecutive fields, then, suddenly we have 3 equal fields
(due pf=1, rff=1). no smooth pan movement would survive.

perhaps we should export this stream frame-by-frame to understand how
is it supposed to be displayed. i tried forcing progressive frames to
be deinterlaced as well and it seemed pretty smooth. maybe the flags
are wrong?

ok, added to my todo list ;-)
