tfields will do this, but I doubt you will be satisfied with the
results.  tfields is also not suitable for playback, only for encoding,
so its use is further limited.

MPlayer has no good deinterlacers.  If you deal with a lot of interlaced
video, you should use Xine instead, and use the GreedyH or TomsMoComp
tvtime method, both of which use motion-compensation and motion-adaptive
processing.  Note also that quality scales proportionately with CPU
usage.  Playback of NTSC video using TomsMoComp (which is just about the
best deinterlacer I've seen) with chroma filtering enabled uses about
60% of my AMD Sempron 3000.  (GreedyH, which is nearly as good, uses
45%.)  So you won't be using these methods to deinterlace high-def video
any time soon.

Cheers,
Jason.
