Jittery picture

I’ve got an M8S (Kodi 16) and I seem to be having trouble with certain TV shows being jittery. I watched a movie last night and it was perfectly smooth, but tried to watch latest episode of Homeland and it was almost unwatchable . Tried different source and also different add ons with no improvement. Quit watching Westworld for the same reason. Also tried using SPMC and no difference.

Is there something different about these shows?
