[mythtv-users] infamous "Access denied" on mythtv-setup/frontend/backend

[Trey Thompson]

well, aparantly I did something to really foul things up.
$ mysql -u mythtv -p -e "show database"
returns the list of databases
$ mysql -u root -p -e "show database"
does also

But, mythtv-setup  gives "Access denied for user 'mythtv'@'%' to
database 'mythconverg'

I haven't made any sql changes.
mysql.txt is the same as it was in October

backend won't start either, giving the same error.

How do I figure out what the heck I did?

I've read about 30 posts to the list for "access denied for user", and
they all point to mysql.txt problems, or Wilson's mysql setup...
