In firefox the flash movie is centered fine, but in IE its off to the left. Any suggestions?

Here is my html/css


<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>multifocal</title>
<style type="text/css">
body {
    margin: 0;
    padding: 0;
}
#content {
    width: 950px;
    margin-left:auto;
    margin-right:auto;
}
#bg {
    background: url(images/bg.gif) repeat-x;
    width: 5px auto;
}

</style>
<script language="javascript">AC_FL_RunContent = 0;</script>
<script src="AC_RunActiveContent.js" language="javascript"></script>
</head>
<body bgcolor="#ffffff">
<div id="bg">
    <div id="content">
    <script language="javascript">
        if (AC_FL_RunContent == 0) {
            alert("This page requires AC_RunActiveContent.js.");
        } else {
            AC_FL_RunContent(
