Thanks.  I have two config.xml files.  One is in /home/mythtv/.mythtv and
the other is in /etc/mythtv

I copied the version from the mythdirectory into the etc directory.  It
looks like this:

<Configuration>
  <LocalHostName>my-unique-identifier-goes-here</LocalHostName>
  <Database>
    <PingHost>1</PingHost>
    <Host>localhost</Host>
    <UserName>mythtv</UserName>
    <Password>mythtv</Password>
    <DatabaseName>mythconverg</DatabaseName>

  </Database>
