I've seen this running SVN for ATSC listings from
DataDirect (ATSC in Fremont, California).  However,
I've only seen this when trying to populate the
channel list while running mythtv-setup (I can't say
that it doesn't happen elsewhere - I haven't really
had a system running for any great duration of time.)

I'm not really sure why it happens, but I noticed that
it started happening after SVN revision 9626 where
mythfilldatabase will no longer insert DVB/ATSC/QAM
channels if the channel number isn't already in the

Also, as a (probably unintended) consequence of this
change, if you forget to scan for ATSC channels (using
the scanner in mythtv-setup), then after running
mythfilldatabase, all channels in the DataDirect
lineup are enabled (including analog), and you have to
go into labs.zap2it.com and prune your channel list

Through trial and error, and many MySQL commands to
drop channel tables, I think I've finally got the
process down.  :)  I haven't yet decided to see if I
can code a fix for any of this, since I'm not really
sure what the intended behaviours on the part of
mythtv-setup, mythfilldatabase, and the user are.
