I used Salling Media Sync to copy over my music, but my playlists wouldn't work until I added "mp3" (without the quotes) as the last line of the .m3u file. Once I gave the Inc the chance to scan everything, it worked fine.

My playlists are in a folder called playlists.

I also found this, but I don't know if it works for us:

Hope this helps someone else.
