I'm using the Minidlna 1.3.0 packaged by Debian. I would like to use playlists. Simplifying, I got a directory called /home/me/music, where files are correctly sent from Minidlna, and a directory /home/me/playlists, where I put playlists. I use simple files m3u, where every row is a file, like /home/me/music/disc/file.mp3. Why they are not displayed, also if I've read that Minidlna supports them? Is there a way to have them usable?
