Hi all. I have a media server running Plex server. Everything works perfectly, movies, music and pictures. The only problem I'm having is it just hangs when attempting to buffer any iPhone movie. These movies are actually from about 6 years ago (so they're not 4K). My Roku is connected via ethernet, plugged into a gigabit switch to a gigabit router. Again, I can stream 4K movies from my Plex server with no problem. The stream settings are the same at 10Mbps (1080p).
