I'm using FLVPlayer in FCKEditor. When I insert the code:
<div style="text-align: center;" id="player358613-parent">
<div style="border-style: none; overflow: hidden; height: 385px; width: 584px; background-color: rgb(220, 220, 220); background-image: url(/Macedon07/fckeditor/editor/plugins/flvPlayer/flvPlayer.gif); background-repeat: no-repeat; background-position: center center; margin-left: auto; margin-right: auto;"><script src="/Macedon07/fckeditor/editor/plugins/flvPlayer/swfobject.js" type="text/javascript"></script>
<div id="player358613"><a href="http://www.macromedia.com/go/getflashplayer">Get the Flash Player</a> to see this player.
<div style="overflow: hidden; display: none; visibility: hidden; width: 0px; height: 0px;" id="player358613-config">url=/userfiles/media/Makedonski pesni/Vaska Ilieva - Imala majka devet sina.mp3 wmurl=/userfiles/image/mac.GIF width=584 height=385 loop=false play=false downloadable=false fullscreen=true displayNavigation=true displayDigits=true align=center dispPlaylist=none playlistThumbs=false</div>
</div>
<script type="text/javascript">

s1.addVariable("width","584");
