CSS on the Embedded SWF File (Min-Width Hack)

I need to achieve min-width: 760px; in IE with a page I'm working on. I'm having some difficulties doing so. I have a code that works, but it isn't working on my embedded flash file. I've tried a few different things, i've applied the style to many different tags trying to achieve the effect. Maybe that's part of the problem, I dont know. Here's the code I am embedding for the flash:

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="100%" height="550" id="splash" align="top">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="multimedia/splash.swf" />
<param name="quality" value="high" />
<param name="salign" value="lt" />
<param name="bgcolor" value="#000000" />
<embed src="multimedia/splash.swf" quality="high" salign="lt" bgcolor="#000000" width="100%" height="550" name="splash" align="top" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />

Here is the css style I would like to apply:

style="min-width: 760px; width: 100%; width:expression(document.body.clientWidth < 760? "760px": "auto" ) !important;"

The site I'm working with is Prince Cummings :: Voice Over Artist. I'm trying to achieve a 100% width but give a min-width of 760px.

At the least, I'm looking for information on how to apply a style to an embedded swf file as opposed to putting the info in as html.
