In VideoOutputXvMC::Show  in videoout_xvmc.cpp the change:-

XvMCPutSurface(data->XJ_disp, surf, data->XJ_curwin,
                   imgx, imgy, imgw, src_h,
                   dispxoff, dispyoff + halfLineSrc,
                   dispwoff, disphoff - halfLineSrc, field);

Appears to be causing the unichrome XvMC grief. If you remove the "+- 
halfLineSrc" the playback will be smooth again for now.
