Sweet! Our new XBMC box is online. It automatically downloads our TV shows from Usenet (yeah, it's still around, apparently) sort of like a DVR without needing a cable hookup. It even speaks UPNP with our Mythtv box so we can use the XBMC box it to watch stuff we DVR'd with the Mythtv box. Might eventually merge the two so I'm not running two PC's in the living room, but I'm afraid to touch the myth box after 4 years of off-and-on hackery.
