Ok, so as luck would have it, a current TV show is being broadcast in Interlaced. I think this is going to be a mute point, but I’ll share links to the files I collected. But I did note that PMS is correctly identified this short recording as Interlaced.
I will be attempting to grab more files, that hopefully span the aired show as Interlaced and I’m hoping that the commercials/adverts will be in Progressive… I’ll report back on that.
@ChuckPa here’s some more files, but they all seem to identify correctly as Interlaced.
