Thanks for all the help guys, and the patience with my inexperience.
1 Coax to a Dual Tuner Reciever: this does NOT jive with what I've learned so far, in fact a few install docs I've seen for dish network show 2 coax running to their dual tuners. Is this the result of the DishPro Technology? Starting to sound like to me, they build in a lot of the features/components of multi-switches into the LNB's and recievers to avoid using Multi-Switches inbetween them. So I guess, a Duo Vip 222k can have a single coax going to the satellite and tune 2 seperate channels to 2 seperate outputs. Any limitation, like both channels have to be on the same polarization, OR its unlimited, get any combination of channel/tuner, they've managed to combined all on the same coax?
Lease vs Buy receivers: The Recievers I get free with the installation, they are actually leased? I'll have to pay monthly fees for those recievers. Do I have the option to buy my recievers and NOT pay monthly fees for them? A quick google search shows Dish Recievers on sale all over for very reasonable prices, granted some or used or refurbished. Can I buy a reciever, hook it up and activate it with my service? As long as its a Duo Vip 222k, I can buy it and avoid lease fees?
Actually, 3 dual tuner recievers may work for me, I have 3 TV's with a dual tuner Recorder, it would leave me room to add another TV in the future.
Now my odd ball out of the ordinary for my setup: HTPC, basically a 3rd party digital recorder. I'd like to connect it to a dual tuner, control it with an IR blaster. Seen some other threads indicating its very possible to control both tuners with the IR port. Granted, the 2nd tuner will be SD. Granted there is NO off the shelf equipment right now for a HTPC to recieve HD, other than clearqam/atsc. BUT, it likely will be in the future, if they ever work out the DRM issues and I can get a cheap piece of hardware to let me recieve the HD. For the moment, I'd be stuck with SD on both outputs, which would also NOT be violating any of the content provider concerns about digital recording, at least as I undertand them.
Will an installer give me a problem about a HTPC, i.e. copyright, NOT inteded for their service, etc reasons, OR is the installer just interested in getting the install done, he's NOT going to get overly concerned about how I'm going to use the receiver. Granted I'd be responsible to get this odd ball combo working NOT the installer. I'm more concerned the Installer would refuse to leave the receiver behind and tell me your NOT allowed to hook this up to that.
