Swiff.remote error "__flash__argumentsToXML"

[Jeremy B]

This might be hard to debug however I am getting this error in firebug:
__flash__argumentsToXML is not defined
http://ngpress.dev.summitprojects.com/resources/js/unpacked/mootools-1.2.js
Line
275


This is the JavaScript Code that I am using.

if($('videoPlayer')){
   var mediaPlayer = new Swiff('./resources/swf/mediaPlayer.swf?'+$time(),{
   id:'recentVideo',
   width: 304,
   height: 187,
   params:{
   wmode: 'opaque',
allowScriptAccess: 'always',
   bgcolor: '#ffffff'
   }
   });
   $('videoPlayer').empty();
   $('videoPlayer').adopt(mediaPlayer);

if($('playVideo')){
$('playVideo').addEvent('click',function (e) {
new Event(e).stop();
var videoPlay = Swiff.remote($('recentVideo'),'playVideo');
});
}
   }

I have had the Flash Developer that built the swf verify that the function
exists in the SWF file.

Any help or ideas would be greatly appreciated,
Jeremy
