SMIL players (such as the IAdea XMP-300, f/w 1.0.21 or later) support configuring a "Content Source" URL which is loaded at boot time. To make a SMIL player play from an Media RSS feed, simply set up a dynamic script (.aspx, .php, etc.) that takes a Media RSS feed and outputs SMIL, then point your SMIL player to the dynamic script.
One way to convert a media RSS feed into a SMIL feed is to use the PHP XPath library.
<?php $doc = new DOMDocument(); if( $doc->load('http://rss.server.com/mediarssfeed') ) // place your feed here { $xpath = new DOMXPath($doc); $xpath->registerNamespace("media", "http://search.yahoo.com/mrss/"); $nodes = $xpath->query('/rss/channel/item/media:content',$doc); $ttlnode= $xpath->query('/rss/channel/ttl',$doc); header( 'Content-Type: application/smil' ); echo "<smil><head>" .'<layout><root-layout width="1280" height="720"/>' .'</layout><meta http-equiv="Refresh" content="' .$ttlnode->item(0)->textContent * 60 .'"/></head>' ."<body><seq repeatCount=\"indefinite\">\r\n" ; foreach( $nodes as $node ) { echo "\t<img src=\"" . $node->attributes->getNamedItem('url') ->textContent . "\" dur=\"" . $node->attributes->getNamedItem('duration') ->textContent . "\" />\r\n" ; } echo '</seq></body></smil>' ; } ?>
