[MPlayer-users] Deinterlacing

Well, that gives an unusual result.  It certainly doesn't need -fps 50, 
because using that makes it play twice as fast.  It *seems* smoother, and 
mplayer's OSD flickers quite rapidly when it's playing (i.e. the OSD is only 
drawn on every second frame) which makes it *seem* like 50fps, but mplayer 
still reports it as 25fps.  Does -vf tfields internally double the framerate?

As rcooley said before though, it does make the picture jump around 
vertically, unless you use -vf tfields=4 or something like that.

Cheers,
Adam.
