I finally set up one of the SiliconDust HomeRun Connect gadgets that I bought a few months ago. When I first bought them, I wasn't sure where I was going to be able to mount an antenna and run the cable, so I thought I might need a tuner in the attic. That turned out not to be the case, but I still had these gadgets sitting around. I'm past the return window, so I figured I'd hook one up anyway, to see if it was useful.

These act as normal TV tuners, hooked up to a normal antenna, with a network output. So once it is connected to power and an antenna, and your home network, many other devices on that home network (wired or wireless) can use the tuner to watch TV. They can be used as external tuners for windows media center, plex dvr, or any other mac/pc setup that needs a tuner. I set up the client on a few of our machines, and it works great. One click, and the app comes up watching live TV.
