If the rss feed comes from a different domain you will be blocked by the 
"same origin policy". If you want to use this plugin with rss feeds 
outside your domain you will need to pass them through a proxy script like this:

<?php
    // PHP Proxy
    // Loads a XML from any location. Used with Flash/Flex apps to bypass security restrictions
    // Author: Paulo Fierro
    // January 29, 2006
    // usage: proxy.php?url=http://mysite.com/myxml.xml
 
    $session = curl_init($_GET['url']);                     // Open the Curl session
    curl_setopt($session, CURLOPT_HEADER, false);           // Don't return HTTP headers
    curl_setopt($session, CURLOPT_RETURNTRANSFER, true);    // Do return the contents of the call
    $xml = curl_exec($session);                             // Make the call
    header("Content-Type: text/xml");                       // Set the content type appropriately
    echo $xml;                                              // Spit out the xml
    curl_close($session);                                   // And close the session
?>
