Plex converting video when I set it not to
Example video file is 6.3 GB (720p, 7000 KB/s video, 1500 KB/s 6-channel DTS audio).
In the Android app, under Settings > Quality, I have 'Internet Streaming' and 'Home Streaming' set to 'Maximum'.
When I stream a movie to, for example, my Chromecast, the app shows that stream's Quality as 'Convert (8.5 Mbps, 720p HD (High)).
It happens with all my video media.
