So, I did a test capture tuning with azap and then played it back using
mplayer.  Sure enough, same problem.  I did this three times and each time
is "froze" in the same place.  Looking at the logs, I see a ton of "a52: CRC
check failed!" but it finally hiccups when this message appears:

alsa-space: xrun of at least 0.119 msecs. resetting stream

Followed by:

Maybe you are playing a non-interleaved stream/file or the codec failed?4 0
For AVI files, try to force non-interleaved mode with the -ni option.

And finally:

alsa-uninit: pcm closed

I tried using the -ni option and get all the sames messages, except the one
about using the -ni option.  Finally, I tried watching until just before the
hiccup and then skipping forward.  As before, this avoided the *freeze*
however, unlike with myth where this would result in video with no sound,
mplayer had both video and sound.

Does that help to track this down?
