.mp4 issues ATV4
So I'm having some weird issues with playback of my media files, mainly movies.
I'm using handbrake to encode to .mp4 using the Apple TV preset (1080/30) and then just changing the audio settings to 5.1 and adding AC3 whilst keeping AAC as well as whatever the defaults are. I'm not changing the screen resolution at all.
For some reason some files will play fine and others come back with the following:
Playback was terminated by the server. Conversion failed. A require codec could not be found or failed to install
I can play the files on other apps but plex doesn't like this. Now it isn't every single movie but random despite them all being done the same way in handbrake.
