<table class="TEDtalks">

 <xsl:for-each select="/rss/channel/item">
 <tr>

 <td><xsl:value-of select="title"/></td>

 <td>

 <xsl:value-of select="media:content/@url" />
 </td>

 </tr>
 </xsl:for-each>
</table>

Have you defined the media: xml namespace prefix? E.g.:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:media="http://search.yahoo.com/mrss/"
                ...
