Thanks for the reference.  I typically only use the extra buffering,
but thought I'd go through all the options given the problems I'm
seeing.  FWIW, I've also discovered setting my minimum cpufreq scaling
to 1.8GHz is enough to avoid the glitches.  Is there already some
facility in mythtv to run an external script at the start and end of
video playback?  Thanks,

Alex
