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.
