Installed the latest beta tonight.
Sony TV 85x950g works
Marantz AVR AV10 working
Flirc USB is working to control Kodi. Everything but a back button works. Cannot launch Kodi, no button for it? Cannot move the mouse with the remote either.
So for me, 3 things to make life wonderful.
Control the mouse, launch Kodi and a Kodi back button
