Currently have Direct TV planning to drop since I bought a new HDTV and they want an exhorbinant fee and new 2 year commitment for upgrading one box from digital to HD. Considering Dish Network and am trying to understand how they hook two TVs to a single receiver. Do they have to run lines from room to room? This is especially critical since one of the rooms I want to introduce service in has no wired jack. The three correct rooms all have a wall jack.
