I'm on a Mac and Air Video HD has been rock solid for me, and played back everything I've thrown at it, faultlessly.
But just in the last week or so, I've started to have error message when trying to play some files.
I've tried isolating the issue, but there doesn't appear to be a common thread.
The error message on my iPhone is is 'Playback failed for XYZ.mkv Media failed to load'.
It happens on around 20% of my files. It doesn't appear to affect by file type - MKV and MP4 are equally affected. Or by file size.
Does anyone have any clues? Could it be connected with the Sierra update?
Thanks in advance for any help.
