<param name="allowScriptAccess" value="sameDomain" />
<param name="allowFullScreen" value="false" />
<param name="movie" value="<? print "$ruta";?>" /><param name="quality" value="high" /><param name="bgcolor" value="#333333" /> <embed src="<? print "$ruta";?>" quality="high" bgcolor="#333333" width="75%" height="75%" name="Index_Flash_es" align="middle" allowScriptAccess="sameDomain" allowFullScreen="false" type="application/x-shockwave-flash" pluginspage="http://www.adobe.com/go/getflashplayer_es" />
