MySpace CSS Absolute Positioning Problem

This problem has been the end of me tonight.

Quick breakdown... This seems to only work when I wrap a flash object in an absolute positioned DIV.

I have a youtube video wrapped in the following CSS properties:

div.youtube-featured { position:absolute; width:286px; height:236px; left:50%; margin-left:-143px; top:-1000px; z-index:8; }

That should take the youtube video and throw it so far off the screen nobody can see it. Now, that's NOT what I want, but it's not happening, I can't move this video anywhere with CSS. If anyone can shed some light on the situation I would be very appreciative.
