XvMC support showing only one field. If you really need that
an hack could be done to increase the frame rate twice and
show one field at time (instead frame).
This could be done and for Xv (using stride hacks).
//you can do that now for vo_xvmc by changing magic value 3 to 1 in XvMCPutSurface//
Well there is yet another problem. Usually the content is progressive
and hard telecined. And this is where rich is right, you cannot
detect these frames and cannot fix them.
Wish You Best
