windows media encoder, run that on your regular usage computer with the video running, then open windows media player on the computer conected to the tv, connect to the ip of your regular usage computer and the port you set up. example 192.168.1.101:8080 I think 8080 is the default port. I hope that isn't confusing.
Just google windows media encoder, I am sure you could find it there with good instructions on using it.
