How Do I Place an Embeded Video Over a Background Using CSS?

Hello world,

I am using dreamweaver 5 and cant seem to get my quicktime movie to play on top of my CSS background image. I am using a large photo as my background image and every time I drag the video file to the code it places my video on top of the background image instead of in front the image and not centered.

Please please help very time sensitive.

THANKS
