On a related note, I think I might write a fidtomp3 tool for extracting tunes from our empeg players here. Sure, JEmplode can sorta do it, but it seems to have issues and crashes every now and then, and misses some playlists/tunes.
So instead I want to just rsync /drive*/fids/ from the empeg to a server box, and use fidtomp3 to create links from the hex-named FID files to a tree of mp3 files.
Then presumably I can use mp3tofid, or a modified version thereof, to go in the opposite direction after merging various playlists.
