A 4-minute demo in which Orbit PM, Ron Trackey, shows off the Windows Live for TV Beta on Vista. here is wahat he says about video:
"[The video] shows me logging into the beta through the Spaces app and search/browse Spaces. I navigate around the Spaces Gallery and then open up a few spaces in the rings as well as perform a search of all of Spaces by using the Search option. From within a Space app, I'm able to view a person's space blog entries, photo albums (even download a photo or two), read book lists, and browse a different space direct from the space's friends list. I also show how to launch different types of Messenger chats with your own friends & messenger contacts using the lower Contact ring. I'm able to start Messenger text & voice chats from the my Contact ring and even make Phone calls out over VoIP. I would have placed a call over VoIP, but I didn't want you all calling me... :)"
