Can't be browsed for (but can be searched for)

Question

The 'Gresham College' podcasts ('Audio', and 'Video') can be nicely searched for, but they can't be browsed for.
The search shows that they really are in 'Education/Higher Education' and yet they don't show when I browse for them.
Does anyone have any suggestions? Is it our fault? Can we do anything about this?

Answer 1

I create another mxml file and compile it into swf again, It
wroks well on localside, but if I try to run it on the web,
all I can see is a grey and blank screen "again".
this time I just put a button in the file:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:Button x="286" y="142" label="Button"/>
<mx:Script>
<![CDATA[
flash.system.Security.loadPolicyFile('
http://140.122.79.118/flexexs/crossdomain.xml');
]]>
</mx:Script>
</mx:Application>
Here is My cross doamin file:
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "
http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" secure="false" />
</cross-domain-policy>
Now I just want remove this app, and reuse my
remoting-and-flash-based developement kit.
