I am getting into real difficulties trying to create playlists. My music is stored on NAS and served on lan by minimserver. I have a number of .m3u playlists which were created a while ago from pop recordings which are all mp3 files. The setup works just fine. The playlists sit in my /multimedia/music directory and all the music files are below that directory thus:- /multimedia/music/genre/artist/album/track.mp3. The playlists use directories relative to where they sit so start Genre/etc. for example:-

/home/alastair/mastermedia/Music/Classic Rock/Bob Dylan
I am now trying to create "classical" playlists from my flac files and I have forgotten how I created the existing playlists. I am trying a couple of options new to me; Clementine and VLC. Clementine, I found, creates .xspf files which I do not need and cannot get to work but VLC allows me to save playlists as .m3u.

The playlists created use absolute paths so I strip out the /multimedia/music/ part of the addresses using kate, (previously used regex with sed) but I cannot get the playlists to work and find a good many unwanted automatic substitutions of %20 in the paths where spaces exist in my data files. All my working playlists have spaces in the file and directory names where they exist in the data, so I assume the %20 substitutions are causing my problems. Am I right and how can I stop them from being inserted. Is this some pandering to windoze? This is what I get:-

I shall now attempt remove all the %20 substitutions and try again but it could be a slow process for me to get the regex right!!! Am posting this for help on how to turn off this function meanwhile.
