FLV Player for external FLV source problem

[DoDe]

Hello...

I just made an new bb code with this options:
Title: Embed FLV Files
BB Code Tag Name:FLV
Replacement
<script type="text/javascript" src="embed/swfobject.js"></script>
<div id="player">"Please refresh page for player"</div>
<script type="text/javascript">
var s1 = new SWFObject('embed/player.swf','mpl','352','201','9');
s1.addParam('allowscriptaccess','always');
s1.addParam('allowfullscreen','true');
s1.addParam('flashvars','&file={param}&frontcolor=#ffffff&screencolor=#000000&controlbar=over&backcolor=#003F86&logo=http://www.dfgrom.com/forums/logo2.png');
s1.write('player');
</script>
Use {option}: No
Remove Tag If Empty; Yes
Disable BB Code Within This BB Code: No
Disable Smilies Within This BB Code: No
Disable Word Wrapping Within This BB Code: No

Everything works just fine when I add a first news on the main page... The video shows correctly.
When I try to add a second news with a video something strange happens. The new news has the video with the url of the older news and the older one dosen't have any video.
Can anyone tell me what I made wrong?

Thank you
