I had a crazy idea to try an HEVC file on my Apple TV. I ripped a blu-ray I had to a 2gb, 1080p HEVC MKV with 5 channel AAC audio and sent it over to the VLC storage on the Apple TV. Low and behold, VLC played it with almost no error. There was one scene of a newsreel with a huge amount of texture that it dropped a few frames on, but other than that it was flawless. And at 2gb, it's clear to see how much more efficient h.265 is over h.264. The future has been here the whole time!
