Indeed.  Indeed...  I was mainly interested because the last time I
re-scanned channels, Myth had a horrible time with my PBS station's
ATSC feed.  It found a 4-100 channel which does not seem to be seen by
my TV's tuner (and missed one of the normal subchannels).  I was
wondering if there was a way to tell if that's what that channel was.
It seems to be content-free from a picture standpoint.

What command line tools will show the vbi data?
