How can I center this recorder on the webpage? The script comes with no CSS.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
	<head>
		<title>recorder</title>
		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
		<script type="text/javascript" src="js/swfobject.js"></script>
	</head>

	<body bgcolor="#ffffff">
		<div id="recorder"></div>
              <script type="text/javascript">
               // <![CDATA[
               var so = new SWFObject("recorder.swf", "recorder", "620", "470", "9", "#000000");
			   so.addParam('flashvars','filename=VideoZ&rtmpPath=rtmp://67.xxx.xxx.xxx/vid/&finishURL=player.html')
               so.write("recorder");
               // ]]>
               </script>
	</body>
</html>
