I was having some issues where, it would play some of my files but not some. Those files it did not play, played in KODI running on another PI2.
I assumed it may have been an artifact from when I built it, the process stuck at "mythtv spawning to fast, stopped", where the screen only flashed; left it for 3 hrs like that. Had to do a hard restart for it to booth up and head to Sarah.
I decided to rebuild the MD again, deleted it in the web admin and did over the process.
Will let you know how that goes
