Set your MySQL Password for mythconverg database

I believe mythbackend will create the mythconverg database and mythtv user, but I'm not sure the password it'll create for that user. Come up with a password, change it (I like to use webmin to do simple database stuff -- if you do too, remember to install it using Synaptic), then save the password in your /usr/share/mythtv/mysql.txt file so mythbackend knows what to use for the password:

#-------------------------------------------
# /usr/share/mythtv/mysql.txt
DBHostName=localhost
DBUserName=mythtv
DBName=mythconverg
DBPassword=mythtvpassword
