Flashloaded newsticker much slower in IE via 3rd party

My main SWF is 28K, xml pulls four 8K subSWFS, AS scroller speed is fastest possible.

Serving it from our server scrolling speed is fine, CPU usage is normal

But I have to actually run this through a 3rd party, Pointroll to be exact.

Once uploaded to Pointroll my scrolling speed is crawling in IE.

Any thoughts on why this would be?

Here is a sample of the type of tag that serves these files.


<script type="text/javascript">
function pr_swfver(){
var osf,osfd,i,axo=1,v=0,nv=navigator;
if(nv.plugins&&nv.mimeTypes.length){osf=nv.plugins["Shockwave Flash"];if(osf&&osf.description){osfd=osf.description;v=parseInt(osfd.substring(osfd.indexOf(".")-2))}}
else{try{for(i=5;axo!=null;i++){axo=new ActiveXObject("ShockwaveFlash.ShockwaveFlash."+i);v=i}}catch(e){}}
return v;
}
var pr_redir="$CTURL$";
var pr_nua=navigator.userAgent.toLowerCase();
var pr_pos="",pr_inif=(window!=top);
if(pr_inif){try{pr_pos=(typeof(parent.document)!="unknown")?(((typeof(inDapIF)!="undefined")&&(inDapIF))||(parent.document.domain==document.domain))?"&pos=s":"&pos=x":"&pos=x";}
catch(e){pr_pos="&pos=x";}if(pr_pos=="&pos=x"){var pr_u=new RegExp("[A-Za-z]+:[/][/][A-Za-z0-9.-]+");var pr_t=this.window.document.referrer;
var pr_m=pr_t.match(pr_u);if(pr_m!=null){pr_pos+="&dom="+pr_m[0];}}else{if((typeof(inDapMgrIf)!="undefined")&&(inDapMgrIf)){pr_pos+="&ajx=1"}}}
var pr_s="ads.pointroll.com/PortalServe/?pid=657286T56720080827170256&flash="+pr_swfver()+"&redir="+pr_redir+pr_pos+"&r="+Math.random();
document.write("<scr"+"ipt type='text/javascript' src='http://"+pr_s+"'></scr"+"ipt>");
</script>
