For the love of **** (insert your deity here), don't wait for, nor then rely on Boxee for your TV. That would be a colossal mistake, as development history shows far too much instability and too many regression issues that will drive you nuts for a system that should simply "just work."

Get yourself a SageTV extender and download the last beta server app (no expiration, the same as released version) to use with the HD Home Run or other HD tuner(s).

Google didn't spend a few million on SageTV because it sucks.
