[mythtv-users] database authentication issues - how do I change usernames?

[Justin Gombos]

I'm having troubles connecting to the database.  If I run:

  mysql -umythtv -pmythtv mythconverg

I get a prompt, and if I type 'show tables;' I get 

  Empty set (0.00 sec)

So it seems the database exists and I can get authenticated, but when
I run mythtv or setup, I get:

  Access denied for user: 'mythtv at mydomain.org'

How do I ensure that mythtv does not append a domain name onto the
username?
