Android for your TV in an affordable package; the Mini XPlus! Looks like you could use it for all sorts of things, too. Wifi, an A10 processor, HDMI, USB; all for $69.99. The Miniand site has a few other hackable platforms that also look interesting.
Check out http://www.playlater.tv. I’ve been researching ways to cut cable without getting the shakes too hard. This looks like a potentially handy tool.

Let us know if you’ve tried it out!
