Hi. When i put the flashvars in de page code it works. But when i put it in the config xml file it doesnt. Talking about the link display vars. I am using JWPlayer 4.3.132. My config xml file is named config.xml.php.
Without config xml and working:
<script type="text/javascript" src="http://www.mysite.com/swfobject.js"></script>
<script type="text/javascript">
var s1 = new SWFObject("http://www.mysite.com/player.swf","ply","520","410","9","#FFFFFF");
s1.addParam("allowfullscreen","true");
s1.addParam("allowscriptaccess","always");
s1.addParam("flashvars","file=http://www.mysite.com/media/video.flv&image=preview.jpg&skin=nacht4.swf&link=http://www.google.nl&linkfromdisplay=true&displayclick=link&linktarget=_blank");
s1.write('flashbanner');
</script>With config xml and not working:
<script type="text/javascript" src="http://www.mysite.com/swfobject.js"></script>
<script type="text/javascript">
var s1 = new SWFObject("http://www.mysite.com/player.swf","ply","520","410","9","#FFFFFF");
s1.addParam("allowfullscreen","true");
s1.addParam("allowscriptaccess","always");
s1.addParam("flashvars","file=http://www.mysite.com/media/video.flv&image=preview.jpg&skin=nacht4.swf");
s1.addVariable('config','http://www.mysite.com/config.xml.php');
s1.write('flashbanner');
</script>config xml code:
<config>
<volume>50</volume>
<bufferlength>0</bufferlength>
<link>http://www.google.nl</link>
<linkfromdisplay>true</linkfromdisplay>
<displayclick>link</displayclick>
<linktarget>_blank</linktarget>
</config>Very weird. Any suggestions?

<linkfromdisplay>true</linkfromdisplay>is a v3 player flashvar, not supported by the v4 player.See: http://developer.longtailvideo.com/trac/wiki/FlashVars#Behaviour
Other than that, your player code and your configuration file look OK.
You will have to post a link to your Test Page so someone can help you further. We can't guess.
