I am seriously thinking about dumping cable for satellite but I would like to know a bit more about it. Is there a place to get some information about how you distribute the signal to several TVs and other stuff like DVRs and VCRs

There are a couple ways of doing it.

1. Use a receiver at each TV, with a home run to a switch or the LNB on the dish. Some LNB's have dual or quad outputs, each of which can feed a switch or a receiver. This allows each TV to watch a separate channel. receivers are available with built-in DVR's, and some are available as dual receiver units, allowing for the recording or viewing of multiple channels. Most remotes are IR, but there are some RF remotes as well, especially with the dual receiver units, to allow the remotes to be used from another room.

2. The receiver will normally have 1 or 2 A/V outputs, and a RF output. The A/V outputs can each drive a TV/video monitor/VCR/DVR. The RF output can also drive a TV/VCR/DVR via the tuner input, and can be extended via standard RG6 cabling and splitters to multiple TV's. All TV's will have the same program. The RF output is normally channel 3/4, but some have frequency agile modulators allowing the output to be on other channels.

Dish and DirectTV use different equipment, with the only common equipment being the coax cable. Each receiver requires a home run to the switch or LNB. There are distance limitations. The cable wants to be RG6 quad shield, rated for 2200Mhz or greater.

You can distribute signal throughout the house via several means. You can modulate the signal onto coax as RF, or you can send discrete A/V signals via cat5 extenders.

Here's an installation manual for Dish.

Thanks
Is one better than the other?

I won't say that one is better than the other, they have some differences in programming, and each has their cheerleaders and detractors.

We have Dish, and we have been relatively happy with it.

With Dish, you buy/lease your equipment from Dish.
With DirectTV you have a wider choice of equipment vendors.

Dish offers DVR units, DirectTV offers Tivo.

Dish seems to have a better selection of HD programming, plus a number of educational channels that DirectTV doesn't have.

Some premium sports packages are only available on DirectTV.

We made up a spreadsheet with all the channel offerings and pricing tiers for both vendors, and selected Dish as having more of the channels that we were interested in.

I am going to keep my ReplayTV DVR until they pry it out of my cold dead hands

The other thing to remember is that frequently the national programming is on the east coast feed, which is 3 hours ahead of the west coast. It probably doesn't matter to you, but it sometimes gets frustrating when another ham mentions an interesting show that he's watching on cable, and it's 3 hours in the past on the dish.
