MinimStreamer Installation

[Imjinman]

Hi

I am pretty new to PC audio, and although I have read the chain I am still not clear.

I have created a m3u file, and I can see this file on my Android (BubbleUPNP) in the Playlist using Minimserver as the Library playlist in the library. I can see two stations: "[ABC] ABC Classic FM" and "ABC Classic FM" (and this is replicated for other stations eg BBC Radio 1. This serves a Moon 180 renderer.

The second one plays fine, but the first doesn't play at all although it appears in the playlist in BubbleUPnPlist. Clicking it results in "Current State of service prevents invoking that action. timeout waiting for playing (code 501)."
What have I done wrong? Or is there a way to hide the first, inoperable item, and just have the playable second option?
Many thanks!
