I saw on my TiVo Roamio that KMSPDT1 from the Twin Cities, MN went from 9-9 to 9-5. I only have my local Rochester, MN locals on my AM21 right now so I can't tell. But if I ever decide to put the Cities locals back on my AM21, would I have to put in a different zip code or did the DirecTV AM21 adjust it? And if I need a new zip code, which one should I use?
