This page embeds a YouTube video using the following code:
<object type="application/x-shockwave-flash" width="425" height="344" data="http://www.youtube.com/v/c6Io05fTLSg"><param name="movie" value="http://www.youtube.com/v/c6Io05fTLSg" /><param name="wmode" value="transparent" /> </object>

The link to the original video is here.
The original Embed code from YouTube is:
<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/c6Io05fTLSg&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/c6Io05fTLSg&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object>
but the <embed> tag is not XHTML-compliant.
There is a web site that will convert such code to valid XHTML:
<!--[if !IE]> -->
<object type="application/x-shockwave-flash"
data="http://www.youtube.com/v/c6Io05fTLSg&hl=en_US&fs=1&"
width="425" height="344">
<!-- <![endif]-->
<!--[if IE]>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"
width="425" height="344">
<param name="movie"
value="http://www.youtube.com/v/c6Io05fTLSg&hl=en_US&fs=1&" />
