I have now manged to detect the itunes library using the mapped drive and UNC path on the NAS.
I had to setup the firefly service to use domain account instead of local system account so it was a permissions issue.
The XBMC now also see’s the itunes library and playlists but all the songs have a number in front of it and they are not in the same order as itunes. Any idea’s?
It seems to be working otherwise.
