Windows 7 - Xbox 360 Streaming Is Buggy For Now, but it Still Works...Kinda

One advantage Windows 7 has over OS X is that you can stream to your Xbox 360 without the need for third-party software. And though it's still rough around the edges, it mostly functions. For those unaware, there are two ways you can stream media to your Xbox: through media center or through your windows media player library. Media Center gives you the advantage of a visually-oriented UI and some advanced features such as live TV and movie rentals. Streaming through the Media Player library, conversely, is an easy, no nonsense way of accessing music and videos.
The problem is, getting everything setup isn't such a breeze. Let's start with Media Center.
