As the user above mentioned, ever since that last update that made the user interface prettier...the buffering is unbearable. My PC is plugged in with ethernet, and my chromecast is right next to my router. Before the update it played 1080p 8-10 GB mkvs with zero buffering; now that is totally impossible. It sucks that this has happened, I was really spreading the work on how awesome this was to my friends and family that have chromecast (over {Plex), but this is unusable now!
