I would like to switch to HD and DirecTV but I'm confused on how everything works right now. I live in rural South Dakota (just south of Aberdeen). Around here you can get the local channels in standard definition through D* and E*. However, OTA, you can only get ABC and CBS in HD. Will I be able to get the national channels of FOX, ABC, ect through DirecTV in HD? It's really kind of confusing on who can get it and who can't.
