Configuring radio streams with minimwatch

[Siriuslux]

I seem to be too stupid to make Internetradio work on my Oppo BDP-105 EU.
The source for the Oppo is my Synology DSM-211+, it runs DSM 5.0. Minimserver and a couple of other things such as BubbleUPNP Server.
I copied the m3u file given further up in this thread to a subdirectory on the NAS which itself is being monitored by Minimserver. The result - nothing - not a single note or sound from one of the Internet-Radio Stations.

If anyone had a hint, I'd be grateful.
