I recently noticed that PleXBMC Helper was not working anymore. PleXBMC just doesn' t apperar as a player anymore.
My PleXBMC Helper is V 3.1.3 on a raspberry PI with Raspbmc.
I updated Plex Media Server to 0.9.8.14 but this didn' t help.
It would be really great to get the ... play on plexbmc ... feature back because the user inteface on the raspberry is so crappy slow, its no fun to use it.
User wickning1 has been working on getting timeline and flinging support for plexbmc. The reason why the Play To feature broke recently is because the feature has been updated across most of the clients since Chromecast support was added.
