Please disregard my last comment, I should have RTFM rather than
anything else. In particular, it was very counterproductive to provide a
wrong field_dominance value...

The quality of yadif deinterlacing appears to be excellent, only the
computational expenses seem to be significantly higher than with xine
and GreedyH: in both cases top reports about 40% CPU load, but at
1000MHz with xine and at 1800MHz with MPlayer. In other words,
implementing GreedyH for MPlayer might at least help the environment ;-)

Thank you for pointing me to yadif.
