Just in case you missed it buried underneath the upgrade to Netflix Watch Instantly the other day, Microsoft has gone live with Internet TV on Windows 7 Media Center, offering content (of rather poor picture quality) from the following providers:
• CBS Audience Network: Featuring a variety of shows from CBS Primetime, Daytime, Extras, and TV Classics, including full-length episodes of current TV shows, CBS Classics TV shows, short clips, and Web originals. • Full Zune Video Podcast Library: Thousands of hours of entertainment with full TV episodes, webisodes, clips, and videos from providers including ABC News, CBS News, CNBC, CNET TV, Comedy Central, Current TV, The Discovery Channel, Fox, G4 TV, HBO, MSNBC, NBC, Showtime, and Revision 3, along with some of the best user-generated videos on the Web. Some video podcasts are also available in HD. • MSN and msnbc.com: Clips as well as full length episodes from TV shows such as Arrested Development, news and weather from MSNBC, editor picks and most popular videos, five day weather forecasts, news, video playlists, music videos, movie trailers and more.
If you haven't already noticed the upgrades in your Windows 7 Media centre menu, you can manually update by going into Tasks >>Settings >> General >> Automatic Download Options.
