I saw an ad this week where you get a free HDTV receiver with the purchase of any HDTV (excluding models with an integrated receiver), which seems like a great deal. Now I'm thinking about getting one, but I have no idea how everything's connected. As it stands now, this is how the cable in my room is set up: wall --> cable box --> vcr --> tv I change channels with my cable box remote. How will things change if I get an HDTV and receiver? Is the receiver like a pass-through box that just goes right after my vcr? Can I still change channels on the cable box? I can't really get rid of it, otherwise I lose all of the digital tv channels (everything above 22). For anyone in the Phoenix area, how many channels are broadcast in HDTV? Is the difference noticeable? Do you need to do anything special to switch between those and "regular" channels? I know it's quite a few questions. Any answers would be appreciated.
