                  MythTV will take care of that for you.  However, I

        <div>It appears that doing a Deleta All Video Sources followed
          by a Delete All Capture Cards does not clear out the three
          channelscan (only two of which perhaps are still used anymore;
          I think the third, &quot;channelscan&quot;, may be leftover in my DB
          from a long time ago) tables in the DB.  I will clear these
