Hmm, the manual says, it only works with mencoder and that I should set 
-fps and -ofps. Since -ofps seems not to be available for mplayer, I 
tried the following to play a 25 fps interlaced MPEG2 movie:

mplayer -vf tfields=4 -fps 50 movie.mpg

This results in a squeezed playback (half the vertical size).
