Instructions to listen to Internet Radio/Stream

[hp1975]

This should be simple right?

My setup:

MinimServer on QNAP NAS
RuneAudio on Rpi2 as Renderer
Bubbleupnp as control point

I have a premium account with di.fm and cannot for the life of me figure out how to get Bubbleupnp to recognise the streams they provide.

I have assumed that the streams need to go inside a EXTINF M3U playlist file, is that correct? However, when i open the playlist inside bubbleupnp they are blank there are no entries to play.

Do i need MinimStreamer as well?

I suspect I'm missing something obvious. Grateful for a bit of assistance for a minim noob!

Many Thanks
