Well I finished installing this on my Mac Mini: Hybrid tuner and Eye TV software.
It essentially makes the Mac a DVR/PVR. The MAC Mini is very tiny and looks great as the center piece of a home theater.
Got a wireless Adesso keyboard with built-in trackpad. I may get a little Logitech DiNovo - but my CFO has not released the funds yet
Mac has 4 GB of RAM, 500GB HD, Intel Core i5 and Radeon HD 6330 video with 256MB of RAM. Mountain Lion.
I am very impressed with performance, the tuner is super sensitive as I get more channels from my antenna than I get with my Sharp 42 Aquos.
The HD quality is great. Software is fabulous, I can record with so many options: series, new run, repeats, etc. Very intuitive. TV Guide provides listings for free for 1 year, $20/year thereafter.
It's nice to have a full fledge computer too.
The total investment (approx $1000) will pay for itself quickly with no cable bill now.
Happy as a clam.
