anyone running a OTA setup at home? There's only 3 OTA HD channels in my zip (68127), but I'd like to see if I can get this to work. I know nothing about this other than i might have to aim the damn antenna at each single... everytime What receiver do you run? My DLP doesn't have a tuner built-in, so I assume I'll need one of those as well. Any thoughts/comments are welcome.
