itunes content not playing via chromecast
I've recently joined plex and just bought google chromecast. Plex has found my itunes movies on my PC and plays it fine through my iphone but when I try to cast it there is just an error code that comes up. BBC iplayer etc. cast fine via my iphone through plex. Is there a way to fix this to allow my itunes content to be be cast from plex or is it a compatibilty problem with apple and android?
