Clueless or my Brain is Dead

[NaisA-]

I am trying to make a video as a background for the home page for my forum. 

I do not know how to get videos to play as backgrounds on IPS. I also do not care about the slow time of my pages, I just want to know how to do this.

Here is the link of the video - http://www.blake-music.com/images/VACation_1.mp4

Colosseum-Gaming.com

Any help is appreciated.
