The DX80 apparently stores the playlists on it's own internal storage. Exporting a playlist will create the Playlist1 in the /m3u/ directory on one of the SD cards. If you edit that Playlist1 then you will have to import it so that the DX80 can read it and store it in it's own storage area.
I do not understand the clicks and restarts. When I was figuring this path stuff out I imported a couple playlists that ended up being empty as far as the DX80 was concerned. But it didn't restart.
.m3u files can have many options. My tests involved a very simple .m3u - just a list of filenames. It's possible that your program is making a more complex m3u, and possibly some option is causing the DX80 to puke. Do you want to send me that playlist and I'll experiment?
Thanks, yeah it is puking for sure. I took one and removed all the & in it but still no joy. I have spaces and hyphens in my filenames, and & in this one.
I'll make a very basic one tonight but this is a pretty student filename template is it not?
