PHP Hot linking script stalling? Help.

[sp0oon]

Hello,

I have a hot linking video script I've added a pop-up script to the php file so that evertime a video plays a pop-under add appears.

Now, for some reason the pop-under stalling up the script sometimes.. Here's how the code looks..

Please not that there is more to this script, but I don't want to post the source code as I had to pay for this script.

<script type='text/javascript' src='swfobject.js'></script>   
<script type='text/javascript'>
var s1 = new SWFObject('player.swf','player','515','350','9');
s1.addParam('allowfullscreen','true');

s1.addParam("wmode","transparent");
s1.addParam("allowScriptAccess", "always");
s1.addParam('allowscriptaccess','always');
s1.addParam('flashvars','file=<?php echo $stream;?>');
s1.write('preview');
</script>

</script>
