that is using rss 2.0 and i think the version of rss that is supported in the script right now is .91.
rss .91:
Code:
<channel>
<item>
<title></title>
<link></link>
<pubDate></pubDate>
<description></description>
</item>
</channel>
rss 2.0:
Code:
<channel>
<item>
<title></title>
<link></link>
<pubDate></pubDate>
<description><![CDATA[ ]]></description>
</item>
</channel>
