N-Stream Play list??

Hi All.

Firstly apologies for all irrelevant information I am about to list. I am not the most technical so I have tried to list all information that may be relevant to help get an answer...

I have an Iphone 4 with the N-Stream app installed (yesterday) to control my SuperUniti (which is 3 weeks old). It works just fine when I enter the SU IP address (because it would not automatically connect) and have the UPnP compatibility mode on but with UPnP on I cant make playlists. Additionally with the UPnP on I can see what is playing but cant access my NAS library.

If anyone has any suggestions as to how I can get this to work properly I would be grateful.

My system set up is as below;

1/SU with firmware 2.0.50.12943

This is connected with cat 6 hard wired link to

2/Netgear Prosafe Gigabit switch.

3/Netgear ReadyNAS102 is also plugged into the Gig switch as are my PC/router etc

4/ Router is a Draytek Vigor2830n with Gigabit ports from BT fibre and to Netgear Gig switch.

5/ My Iphone is an Iphone4 software version 7.0.4, model MC605B/A with modem firmware 04.12.09 (date??)

I have the wireless off on my SU as I am using a hardwired link and all IP addresses are fixed (they were fixed in the router by our company IT bloke)

Any suggestions or help would be gratefully received!

Best regards, 

Kevin.
