The Fall 2011 update for the Xbox 360 brings a great new Metro-style UI to the Xbox dashboard, but where did Media Center go? You can still use your Xbox as an extender, you just have to dig a little to find it. The Media Center extender application appears in both the Apps section and the Videos section. And, of course, if you’re using the Media Center or Xbox remote, you can always just push the green button!
If you’re using your Xbox primarily as an extender, you may just want to consider having it launch Media Center automatically each time you turn it on. The attached video shows you how to Launch Media Center from the new Xbox dashboard and how to automatically launch Windows Media Center on startup.
