Finally, the 'map base file paths in exported playlists' setting is ignored as well. In addition, the file path is in Windows format even with 'use unix path convention' checked. M3U files are exported with absolute paths even with 'use relative file paths' checked. * Exported M3U playlists do not follow the settings specified in Preferences -> Library -> playlists. That patch supposedly resolved issues regarding M3U functionality, but as far as I can tell all it did was disable the screen for setting options regarding M3U playlists.
