For Directv you will need an elliptical dish with a 3 prong LNB, a HDTV receiver (try Samsung or Hughes) and a TV with built in monitor. If your TV doesn't have the built-in monitor, you will have to also get a converter. Now this will get you HDNet, DiscoveryHD, ESPNHD (July 1, will be part of a subscription), HBOHD (must subcribe), ShowtimeHD (must subsribe) and pay per movies in HD. For local HD channels, you will need a seperate antenna to pick up those channels. Because of this I recommend the Samsung TS160 receiver. That way you can hook both the dish and the antenna up to the receiver and let it do the switching (only need one remote). Most other HD receivers do not have the antenna hookup, therefore you will need to connect the antenna up to the back of the TV (you need to use two remotes: one for HD over the dish, one for HD from the antenna).
