Hi Whitepine,
Unfortunatly, I don’t think I will be of much help. For testing purposes I’ve been using winamp. To actually populate my SD cards / player I have a custom program I’ve been working on that takes the lists I made and saved on my NAS, transfers the linked files, then creates a new m3u8 on the sd card, by creating an empty file with the BOM up front and linking all the copied files. Haven’t actually done much of the management on my *nix boxen.
That said, I believe both VLC and XMMS will save m3u8’s. VLC saves the wrong file extension (at least on windows) but the BOM is still present so you just need to redo the extension for devices/apps that require the m3u8 file to use the m3u8 extinsion. Sorry for not being as much of a help.
