I tried to burn a CD that has a playlist (.M3U file), followed by a folder with the same name (without the extension), and all my MP3 files within this folder. Still played in burn-order, not playlist-order. I used Nero 6.6.
How do I burn a CD that will play a playlist of MP3s? The manual was not too clear about that. I've tried to include a .m3u playlist file, but the head unit ignores that file.
