MP4 files are converting to MKV for what I have narrowed down to be having multiple audio tracks. This breaks dolby vision as roku doesn’t support DV in MKV. If I turn Direct Play to Force they play fine.
While testing some files also got the Playback Error screen, they also played fine once Direct Play was Forced.
