Flash embed ideas for Internet Explorer?

We're trying to embed a flash banner without using a plugin on this page: http://firstsouthtx.com/company/contact/

The code below works fine in all browsers except Internet explorer unless we remove the "classid="clsid:smiley:27CDB6E-AE6D-11cf-96B8-44455354000" section, anyone know if this might create issues when we remove this section?

Also, in your experience, are we going to have issues once we start trying to embed youtube and related movies if we don't use plugins?

<object  classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"  codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="500" height="232">
<param name="movie" value="banner.swf" />
<param name="quality" value="high" />
<embed src="http://firstsouthtx.leadpress1.com/files/2009/12/banner.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="500" height="232"></embed>

Any feedback appreciated!
