I'm always apprehensive when I have to fiddle with 'hostnames' after the 
initial setup.  I haven't consulted the wiki about it recently but there 
used to be some fairly arcane procedures there.

FWIW my config.xml (sl7) has:

<Configuration>
   <LocalHostName>hpbox</LocalHostName>
   <Database>
     <PingHost>1</PingHost>
     <Host>localhost</Host>
     <UserName>mythtv</UserName>
     <Password>xxxx</Password>
     <DatabaseName>mythconverg</DatabaseName>
     <Port>3306</Port>
   </Database>.....

...and the response to the 'hostname' command is intentionally different 
from either of the two names above.
