I am trying to use the upnp function of my NP1100. It sees my upnp server (Yazsoft - Playback) and I can navigate to a
folder but the NP1100 won't show me it's content although there is a valid mp3 and aac audio file. Instead it gives me the
above message. All of my other streaming clients (Grundig Cosmopolit 7 Web, Fantec S3600) are playing these files.
