Yes, I did, but no, it did not.

There already was a mythconverg database. See below.

I got an error message (now lost) when I tried this. I ran

select user, host from mysql.user;

and found that was a mythtv user at host %. I was not able to set a password for it
(as per a couple of lines down in the instructions), nor was I able to create user mythtv @ localhost, or set a password for it.
Probably being too clever, I dropped and recreated database mythconverg, and then
dropped user mythtv and recreated it. Then I was able to finish the rest of this set of instructions.

I ran

mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p mysql

It appeared to run normally, with the noted warnings seen on the 

Next I ran mythbackend from the terminal. Lots of errors related to 
mythconverg being empty. I'm guessing that I shouldn't have dropped it 
and recreated it. An example error message is

Database error was:

Table 'mythconverg.settings' doesn't exist

Where can I find the instructions for creating the innards of mythconverg?

Or, is there something else I need to do?

Thanks for your help.
