I too had an issue with jerky playback on v31 using a Pi 4. My wife said it
was OK to her, but it actually made me start to feel a little nauseous
after a few minutes of trying to watch a hockey game.

Then I found this:  https://www.mythtv.org/wiki/Raspberry_Pi#RPi4_Specific

It uses "MMAL" as decoder; I have no idea what that means, but when I
followed the directions here to set up a new playback profile and set
Mythfrontend to use it, it now works flawlessly with no jerkiness.
