Over in building 50 there's a secret room. It's never been shown in public before. What is this room for? Testing audio devices. It is a special room where it's completely silent and the walls have been treated to minimize sound wave reflections. After giving us a tour Charlie Owen, PM on the Media Center team, gives us a little taste of Windows Vista's Media Center features and shows us how to build your first Media Center application. Great discussion of Xbox 360 and the latest in Media Center functionality. The Vista demo starts at about 19:00 into the video. The Web site we talk about is the Media Center Sandbox, which is where you can learn more.
