Antenna TV on Thursday started airing "That Girl". I noticed that not only did the episodes look less sharp than my DVDs of this show, but also its occasional showings on MeTV over the years. Do diginets like Antenna, MeTV, Decades, Cozi, etc. use the same episode sources? Do they use film, tape, digital files or what? And if they do why do the same shows look different on other channels?
