Does Roon still have the limitation on only importing tracks in the same root folder that the playlists is in?
I have a lot of playlists referencing tracks from different root folders (e.g., I keep my dsf files on a separate NAS share). Neither JRiver nor Minimserver have any problems to import and happily play these playlists. I can also put the playlist in any folder irrespective of where the music is - as long as the filepath for each track is correct and I point the import function at the right folder it will import and play.
With Roon so far I have not even been able to get the program to read any of these playlists no matter where I put them or in which ever way I write the file path in the m3u. If there is a way to do this that I have missed in my search of the forums please let me know.
Otherwise it seems strange to me that a program as powerful as Roon cannot do something as basic as this.
