MythTV pre - 0.25 was jitter/judder free with refresh rate / video
framerate mismatch.
Your xorg.conf setup seems to be at odds with the judder-free wiki.
The common use-case is bad EDID & requirement to force a VESA mode or
custom modeline.
You are using EDID modes & no dynamic twinview.
Dynamic twinview is/was required to allow meta-mode unique (fake)
refreshrate reporting to xrandr.
You are blocking VESA modes.
You have no monitor section (no vert/horiz freq ranges)
You have no screen in device section (prob not matter with one screen)
mythfrontend -v playback
might provide better info.
Can you run "nvidia-settings" & try each of the listed display
resolutions & check what your TV reports.
