WMV files in IE

Hi,
When I add the following code in HTML:

<br>
<div><object width=”320″ height=”256″
classid=”CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95″
codebase=”http://www.microsoft.com/”&gt;
<param name=”autostart” value=”0″ />
<param name=”autoplay” value=”0″ />
<param name=”clicktoplay” value=”1″ />
<param name=”controller” value=”1″ />
<param name=”pluginspage” value=”http://www.microsoft.com/&#8221; />
<param name=”target” value=”myself” />
<param name=”type” value=”application/x-oleobject” />
<param name=”src”
value=”http://url.wmv/></object></div&gt;

…and hit ‘Update’, only the following will appear:

<div><object codebase=”http://www.microsoft.com/&#8221; height=”256″ width=”320″ classid=”CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95″ /></div>

Why does my HTML not get retained?

Thanks
Neil
