Comment (by madscientist159):
I've updated the patch to use the output framerate instead of the source
framerate. This was messing up my initial analysis since MythTV can
select 60Hz output rates for 30FPS content.
It looks like a small static delay (under 100ms) plus 6 frames of delay
just about handles the A/V sync problem completely when switching from
24FPS to 60FPS. I do use the GL renderer, so I wonder if there's some
extra video buffering in the host stack as well that's contributing to the
overall delay.
