Logitech Media Server and UpNP

Hi,

I have just upgraded to version 7.7.1 of LMS.  Apparently it is supposed to now act as a UpNP server as well as a squeezeserver.   However I don't think this is working.

 I have checked the appropriate plugin is enabled.   The app I used on my iPhone called PlugPlayer is not seeing any UpNP server.

Can anyone who has got this going tell me if there is any other setup I have to do or indeed what might be the path to the UpNP server that I can try to add manually...

eg  serverIP:9001/something

thanks a lot
