PS3 Media server and 2 WHS servers

[Triplefun]

I have just installed a second WHS server also configured with PMS and pleased to see 2 'icons' apprear on the PS3

However, when I add a reference in the first WHS server (server1) to the media on the second WHS (\\server2\videos) I cannot see the server2 media when accesssing server1 instance of PMS on the PS3
