Yes: I've just looked at two UK DVB-T2 HD .h264 recordings converted
(in February) to SD mpeg2 using 'mythffmpeg -target pal-dvd', as in
mytharchive.
mediainfo shows that the original input HD is
'25.00 fps 1920:1080 Component:Progressive'
and the output SD is
'25.00 fps 720:576 PAL:Progressive'
so mythffmpeg has not done any deinterlacing in this case.
I've also found one HD recording with 'Component:MBAFF' - known to wiki
but not previously to me.
I don't remember noticing any deinterlacing artefacts on the few DVDs
I've burned from HD recordings - but apparently my DVD player upscales
to 1080p anyway...
