Thinking I might have the same problem. I’ve noticed that playback of 1080p original quality is resulting in a lot of buffering/stuttering–but only on certain clients: Namely Vizio app and Android app. Playing the windows native app doesn’t result in the same problem and doesn’t appear to force CPU usage. Forcing transcode to next step down (20Mbps) spikes cpu usage (system 60% media server sub 20%) with associated drop in quality.
