> The backend where this is being generated from is Xubuntu 16.04 with mythtv v29 ppa.  Is this possible something with ffmpeg or libav? Is it possibly something in mythtranscode?

> Anyone having issues with unplayable hls streams? Can someone run that validate-hls tool on their own streams and verify what I'm seeing?
