Yes it does, but it would mean not having to run 2x media servers and also having multiple metadata libraries. Just a dream anyway, it is beyond the scope of this app.
So has this plug-in died?
It shows up as compatible on MP 1.4, but the plug-in is empty in the GUI ?!
Well, trying out Plex, and finding a possible solution to intergrating it with MediaPortal, I was disappointed to find that development hasn't happened on this for quite a while...and the possible solution is right there.
Anthrax needs to add the PIN code procedure so the server can connect to the client properly. I discovered that attempted connection when looking at my.plexapp.com/devices to see that MyPLexMedia made an attempt to connect. The difference between a successful connection and one that isn't is the entry of the PIN ID.
Hopefully Anthrax will come back and update this someday.
