A Mac Mini HTPC that emulates Dish Network's Dual Tuner system?

Hi 🙂

Please forgive me if this has been covered and answered in another thread.

I would like to do a HTPC set-up but want to emulate the capabilities of Dish Network's dual tuner DVR capabilities, and not have to pay their monthly rates. I would like, therefore, to:

-- record 2 shows at once, ideally while also being able to watch OTA TV channels separately, but that latter part is not a must-have
-- have the ability to connect the HTPC over 2 separate TVs, so that I can watch live TV or a recorded show on one and my wife has the ability to watch what she wants (live or recorded as well)on the other; in other words, a whole home DVR.

Not sure if HD Homerun -- which sounds great -- would work in my case, as my router, or, rather my Uverse residential gateway -- is affixed to one of the walls of my garage. Thus, as far as I understand it, since it is away from the living room where my main TV is, it therefore it would be impossible to connect router, antenna and HD Homerun together (right?).

The basic set-up, I know, would be: Digital antenna to TV Tuner (e.g. Elgato) to Mac Mini (connected to an external HD) to TV. Is there anyway to adjust the set up so I can send the output to 2 TVs that can access and view saved material independently from each other, or am I going to have to suck it up, as I fear, and buy 2 of everything and have each set up connect to a central HD (a time capsule perhaps?)?

Hope this made sense; any solutions would be greatly appreciated -- I have been racking my brains for months on this! 🙂

Thanks 🙂
