Nvidia vdpau prog to interlaced transitions show old frames

Related to #13594. In the UK watching DVB-T2. Some recordings are transitioning between interlaced and progressive many times per recording, possibly because of commercials. The playback is a little bumpy and occasionally I see a single frame from many seconds ago that is out of sequence. Does the Nvidia hardware deinterlacer use old frames to construct the deinterlaced image? I can only guess that it does and that in switching from progressive to interlaced it uses a frame history that was stored the last time interlaced material passed through it.

Can you add a complete 'mythfrontend -v playback' log that includes one of these transitions. Thanks.

Had the wrong profile selected for my hardware - changed the deinterlacer to low and the problem has gone. Please close as invalid.
