How to add divx direct movie link to stream movie on web site?

I am trying to make a website where I can paste a divx movie link and stream the video like it is done at this site:

I have poured over the "view source" and can only conclude that he uses a php script. I have seen action=add2.php.

Does anyone know the php needed for this or maybe how to do it if php is not needed?

(I am not talking about embedding a video)

I have read the Webmaster SDK and find nothing about it.

Thank you.
