How do you transfer videos from your PC to your xbox 360

You can stream videos to your Xbox360 by using Windows Media Centre Extender.
To do so bring up Windows Media Centre,
and click Media Centre Extender and it tell you to put in some sort of port number
on your Xbox that's when you select it on your xbox,
I cant be much more of help so I suggest you look it up on UTUBE
Im sure someone has posted a video showing you how... Thank You
