Possibly, though my MP3 test album is transcoding normally. I should have checked the log , and now see the message

HTTPSource: unknown host for URL http://radio.linnrecords.com/cast/tunein...aylist.pls

on the log for the NAS installation

Yes, I'm getting that kind of error from the PC installation. Here is the log message:

Error: playlist Playlists/test.m3u: duplicate stream ID 'Linn'
MinimServer[Bridge] is running
MinimStreamer: transcoding converter is 'C:\FFMPEG\bin\ffmpeg.exe'

What I don't quite understand is that I don't get this error on the NAS, even though the playlist files are identical in both installations. Nor am I sure why the location of FFMPEG is (correctly) displayed.
