New member, strange streamer behaviour

[MaBo]

Hi Minimstreamer/server friends,
As mentioned in my other post, I experience some strange behaviour in playing radio streams on my Cyrus streamer.

If I understand the documentation and forum infor correctly, a playlist file like this should work:
#EXTM3U
#EXTINF:-1,Radio Paradise Main
http://stream.radioparadise.com/flacm

However, it doesn't

What does work is:
#EXTM3U
#EXTINF:-1,[+Radio Paradise;flac] Radio Paradise Main
http://stream.radioparadise.com/flacm

As I don't have a minimstreamer licence, this only shows one stream on my Cyrus streamer.

Why do I have to add the part between [ ]?

Any ideas?

Kind regards,
MaBo
