Ok, I know what causes this now and I'm pretty sure it's a bug:
If I start myth then go into the "Watch recordings" screen the cpu jumps
to 30% while it plays the preview window. When I leave this screen and
go back to the main menu it appears as if it continues to play because I
keep getting "'video_output' mean = '33397.48', std. dev. = '4863.15',
fps = '29.94'" in the log file.
If I disable the live preview in the setup screen this problem goes
away. I believe this is why I was getting jerky video as well because it
was playing it twice.
