 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.
