How do I allow Real Player streaming through on ISA2004 and GFI WebMonitor?

I am trying to get live Radio working through our ISA 2004 proxy server.  I am trying to listen live to BBC Radio Cambridgeshire.  If I bypass the proxy then the radio streams with no issues.  I need to get this working through ISA as the user cannot bypass it.

The radio station in question plays through Real Player.  I have read numberous forums and these are the configurations I have tested:

ISA Firewall - I have created a policy to allow PNM (7070), PNM Server, RTSP (554) and RTSP Server.  I have even created a new PNA protocol on port 1090.  From and To are set to Anywhere.  All Users are allowed.  The schedule is set to always, and all content types are allowed.  This policy is in order no 1.

When I monitor the PC on the the ISA Firewall it does not pick up the above policy as the protocol it is using is HTTP (we already have another policy in place for this).

A general error has occured
More information is available at the RealNetworks Customer Support Website.

I have looked on the Real support site but can't find anything.

I have configured RealPlayer to use the Proxy Server for the Media Browser Proxy Settings.
Streaming Settings have been set to No Proxy, and also proxy server for PNA and RTSP Proxies.
Network transport protocols have been set to Recommended, and also HTTP only.

We are running GFI WebMonitor to scan files for viruses.

We are using Websense Hosted Inernet Security to filter web access.

SOLUTION - We have an external firewall - Cisco ASA firewall go to Configuration, Access Rules.  Add in a new access rule to allow source (PC ip address) to any (destination), using the service TCP (rtsp).
