two updates:
1) Playlists - finally found out how to get them to work (at least with my setup).
NOTE: I had posted a separate topic just for this but for some reason the evil moderator decided to simply lock it down with some strange, rude message about posting a topic twice ... I was not trying to post the topic twice but was trying to find a solution to the problem and I did not find anything in any existing topic that covered it (again, at least in my setup). So, I apologize for that but perhaps those looking for an answer will find this post and get the solution that may work for them.
The problem, as other may have discovered but perhaps not worded this way, is that the playlists you create in Itunes are stored in the Itunes Library files, not as external files in some folder. So, when your Linkstation Media Server database is refreshed it never finds them as it is not looking in the Itunes library files.
So, to get them as files so your Linkstation Media Server will find them, you need to find a way to Export the playlists, and them store them somewhere on the linkstation where they will be found. Here is what I did.
a) I used a free software program called ITunesExport which will allow you to open to an Itunes database, select which Playlists you want to export, and then same them as .m3u files.
b) I then created a folder called Playlists under my Linkstation\Media\ItunesMaster folder (where my library is stored).
c) then I copied the exported .m3u files into the Playlists folder created above
d) logged onto my Linkstation Admin page, went to the Media Server page and refreshed the database (I chose to recreate it too).
Gave it a few minutes, then went to my Roku Soundbridge, connected to Linkstation (the second entry - see below) and there were my playlists. Clicked the one I wanted and whamo! Success!!
Hope this helps others...
2) Soundbridge appearing twice on Roku - still happening, no idea why or how to fix. The previous suggestion did not work in my setup. One thing to note though, the first entry appears and the Playlists option is empty and I cannot find anything with the Browse features - looks like an empty database. The second entry is the one that has my Linkstation media, etc in it and the one that works.
