Button version doesn't work

Strangely, I have the slim line version up and running on an icecast feed (radio).

But I am unable to configure the button version to work with the same feed.

Parametre.as:
autoload = "true";
autoplay = true;
song_url = "http://mysubdomain.mydomain.com:8000/radio128";

Object tag:
<object type="application/x-shockwave-flash"
data="musicplayer.swf?&autoplay=true&song_url=http://mysubdomain.mydomain.com:8000/radio128&playlist_url=http://mysubdomain.mydomain.com:8000/radio128.xspf&playlist_size=1&"
width="17" height="17">
<param name="movie"
value="musicplayer.swf?&autoplay=true&song_url=http://mysubdomain.mydomain.com:8000/radio128&playlist_url=http://mysubdomain.mydomain.com:8000/radio128.xspf&playlist_size=1&" />
<img src="noflash.gif" width="17" height="17" alt="" />
</object>

What am I missing here?

Any help appreciated.

But are you using Wordpress??
If you're using just the .swf you should check what the php plugin generates to make a button player.
