I'd hate to have to go back to an HTPC. I did that in the early HDTV days and just watched on my PC monitor. Today, I'd have to buy ANOTHER PC and install it next to my main TV, rig it with my Onyko and program the ole' Harmony to yet another configuration. And then listen to my wife and MiL ask why it can't just be simple.
Not a thrilling prospect. My ViP722s may be with me a long time. Or there's always Fios. They have a LOT more local channels than Dish.
That's an old style HTPC hook up. I run mine from one side of my living room to behind my entertainment center using an HDMI to dual CAT 5 cable. Then at the other end it converts the CAT 5 back to HDMI. Works great and the line is around 50 ft to the Yamaha 7.1 a/v receiver then HDMI to 42 " Panny Plasma TV monitor. If you have to go to a longer run you use CAT 6 for a run I think of 100 ft.
