After your media has been shared, navigate to your Xbox 360 dashboard.  Select "My Xbox" and then select "Video Library".  Your media should be listed under your computers name.  Select the computer name and then choose the correct folder.  It should not be much different from navigating Windows Explorer.  After doing all of the above actions, you should be able to stream all the media that is shared on your computer with your Xbox 360.
