I am glad you are finding it useful
I will look into the syncing issue and try and work out what is happening.
Can you give me some details about your setup, i.e.:
- Hardware you are running LMS on
- OSX version
- Indigo version
- Logitech Media Server version
- Squeezebox models and how they are connected - wired or wi-fi
- How many Squeezeboxes you have sync'd
Do the Squeezebox Players re-sync themselves if you press <- (back) to restart the track?
Feel free to PM me the info if you want.
