I don't like it.

Your patch tries to artifically increases the framerate 2 times.
However to do so, it uses sleep inside the vo and effectively cuts the
available time mplayer could work 2 times.
Correct handling would require codec or/and mplayer.c sync code tweak.


The other much bigger drawback is that it have hardcoded field order
ignoring top_field_first flag in mpeg-2. At least this is easy to fix.
