Ron, I’m not sure if we have our wires crossed here. 🙂
I have one playlist that I created in iTunes. That shows up in iTunes, soundbridge and XMBC ok.
I then have lots of smart playlists that I created using the mt-daapd web interface. Those show up in Soundbridge, but not iTunes. The names show up in XMBC but not the contents.
I hope that helps.
