OK, did a little bit of googling, read the wikipedia article on HD, etc., still am a little fuzzy on the details. Background: I currently do not own an HD or flat-screen TV -- still stuck with an old gargantuan tube TV. Planning to buy my first plasma or LCD soon. I have Dish Network, happy with them. Have a DVR and love it (one receiver for two tube TVs - one in the living room, one in the bedroom.) So... if I want to start watching things in HD, what is it going to cost me with Dish? I assume I'll have to trade my regular DVR in for an HD-DVR? And then do I have to pay extra per month for HD channels, or is it as simple as turning on an HD-ready TV and then I can watch everything in HD? I ask because I've been reading about stations broadcasting in HD OTA, but I assume I would need a good old-fashioned antenna on the roof to pick those up? But most importantly -- what am I going to need in order to watch the WC this summer in HD, and how much extra is it going to cost me per month vs what I currently pay Dish? Thanks, y'all.
