No, the swf file makes a nice shade on different resolutions/window sizes and also makes it fit.
Try not including a size defintion in the embed tags.

If you checked the scource of the html file you could have seen he already added the title:
HTML Code:
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>index</title>
</head>
as for centering it won't fix the scaling problem.
