Hello all. We recently ordered our first HDTV and it should be here some time next week. I have a PS3 but I realize to get the most out of HDTV when watching the tube is you need an HD source from your cable/satellite provider and mine is DirecTV.
My question is, what all changes with my installation? Do they add a dish or will they take the current one down and replace it with one that can receive the HD signal? Will I have two dishes?

Will they have to replace all the wiring? Will I need a new receiver for each TV or just the HD set? Anymore drilling?

Anything else you guys think I should know about upgrading?
I apologize for all the questions but I found this site doing a Google search and I must say it is top-rate for satellite provider information based upon what I've read. I hope somebody can help me with the questions I have. TIA
