I just purchased a Philips Flat Screen 37PF7320A/37 Last year I had a failure of the LNB on my 10 yr old DirecTV dish so I replaced it and upgraded to a 3 LNB digital dish with 2 digital STB's. Okay, so now I have the HDTV and want to upgrade to HD source material. I have both basic cable (analog) and the D* source material in the house but neither is HD. What I need to do is get HD source material to make some decisions about the TV and then decide which provider I should use long term for my HD source. I mistakenly thought (true rookie) that the Digital satellite system would process the HD source material. I call D* to turn on the HD and they tell me I need the HD STB and will gladly provide it for $99 bucks with a 2 yr contract. I currently own all my own equipment and don't want a contract. So here is my question - Do I need both an HD dish and an HD STB or can I just purchase a new STB to make this work???
