ActiveX is blocking the flash, use swfobject to display the flash content. Get the js file from here
http://blog.deconcept.com/swfobject/
And use this code
<script type="text/javascript" src="swfobject.js"></script>
<div id="flashcontent">
This text is replaced by the Flash movie.
</div>
<script type="text/javascript">
var so = new SWFObject("http://dfidistribution.com/mediaplayer/player.swf", "movie", "320", "240", "8", "#336699");
so.addParam("file", "http://dfidistribution.com/flv/defonce_6.flv");
so.write("flashcontent");
</script>
