Moving to mythtv-users, then.

The LocalHostName in mysql.txt is an override.  If you do not want to 
override the system hostname, do not set it.  That's why it's shown in 
the example mysql.txt distributed with mythtv as:

# Set the following if you want to use something other than the
# machine's real hostname for identifying settings in the database.
# This is useful if your hostname changes often, as otherwise
# you'll need to reconfigure mythtv (or futz with the DB) every time.
# TWO HOSTS MUST NOT USE THE SAME VALUE
#
#LocalHostName=my-unique-identifier-goes-here

Note the "if you want to use something other than the machine's real 
hostname".

It sounds like you just want to use the machine's real hostname.

If you're using the override because you changed your machine's real 
hostname, then just fix your DB:
