Thank you for trying that – I actually do think I can see what’s going wrong.
I just need to know what the first few folders are called when you browse that DLNA server from a traditional UPnP control point. If you install something like the free mConnect lite app, what are the first few folders called? It might be something like ‘Music’ -> ‘Albums’, ‘Songs’, etc. If you send me a screen shot of the first few screens then I should be able to get this going for you.
