just to make you understand what's going on: mplayer has some
crazy and completely broken code in libmpdemux/video.c that tries
to detect and inverse the soft-telecine flags, changing the framerate
from 30 to 24 fps, even when the telecining pattern is different
(such as from 24 to 25, or from 60 to 24) ...
