The version of ffmpeg that ships with 0.26 is rather intolerant of
damage in the video.  Especially on one channel, I had a lot of
mythcommflag failures with status 140.

The latest development version of myth bundles a new version of ffmpeg
which is MUCH better, and I have not had a single mythcommflag failure
with it.  Note that by definition, the latest *development* version is
a moving target, and my not be bug free.

Before anyone asks, it is *extremely* unlikely Myth 0.26 will be
repackaged with the new version of ffmpeg.  Stock ffmpeg is missing a
lot of features that Myth needs, and modifying ffmpeg to work with a
given version of Myth requires a substantial amount of effort.
