Yes.  Can the problem be fixed?  (la la la...  not mentioning
threads...)

tfields halves the height rather than halving the FPS, so it's
throwing away half the picture as well.  What tfields does may be more
easily reversible than what pp=lb does, but either way, you lose about
half.

Of course, if mplayer could properly playback interlaced video on an
interlaced display, I wouldn't have to throw away anything...
