FWIW, you can configure the backend to run mythtranscode *first*
before running mythcommflag. As a bonus, mythcommflag runs faster (if
you resize to a smaller resolution, presumably because the frames to
be analyzed are smaller post-mythtranscode). I haven't noticed any
real difference in (mis)accuracy of commflagging when running before
or after mythtranscode.
