Я окончательно использовал объект SWFObject так:
<html>
<head>
<title>Qcu - CIP UTBM © 2010</title>
<meta name="author" content="Rémy HUBSCHER"/>
<style type="text/css">
* { margin: 0; padding: 0; }
html, body { width: 100%; height: 100%; background-color: #3f3fFF; }
div, object { width: 100%; height: 100% }
</style>
<script type="text/javascript" src="js/swfobject.js"></script>
</head>
<body>
<div id="quiz_content">
<object type="application/x-shockwave-flash" name="quiz" id="quiz" data="swf/quiz.swf">
<param value="swf/quiz.swf" name="movie"/>
<param value="true" name="play"/>
<param value="true" name="loop"/>
<param value="true" name="allowfullscreen"/>
<param value="always" name="allowscriptaccess"/>
<param value="high" name="quality"/>
<param name="wmode" value="window" />
<param name="scale" value="showall" />
<param name="flashvars" value="xml_file=XML/quiz.xml"/>
</object>
</div>
<script type="text/javascript">
var flashvars = {
xml_file: "XML/quiz.xml"
};
var params = {
wmode: "window",
play: "true",
loop: "true",
allowfullscreen: "true",
scale: "showall",
allowscriptaccess: "always",
};
var attributes = {
id: "quiz"
};
swfobject.embedSWF("swf/quiz.swf", "quiz_content", "100%", "100%", "9.0.0", false, flashvars, params, attributes);
</script>
</body>
</html>
