Mike,
I haven't had the time to reinstall (family is hooked on Mythtv and isn't fond of down time), but 
here is the config file I was using. When I have time I will reinstall and report back.

# Monit control file

# Comments begin with a '#' and extend through the end of the line.
# Blank lines between program entries are ignored. Keywords are case
# insensitive. All path's MUST BE FULLY QUALIFIED, starting with '/'

set daemon  30
set logfile /var/log/monit.log
set mail-format
 { from: mike at XXXX.site}
set alert mike at XXXX.site  # Send alert to system admin on any event
set httpd port 2812 and
    allow XXXX.site
    allow 192.168.1.0/255.255.255.0
    allow 127.0.0.1
    allow admin:monit     # user 'admin' with password 'monit'


check process mythbackend with pidfile /var/run/mythtv/mythbackend.pid
 #group mythtv
 start program = "/etc/init.d/mythtv-backend restart"
 stop program  = "/etc/init.d/mythtv-backend stop"
# if failed port 6544 proto http then restart
 depends on mysql

check process mysql with pidfile /var/run/mysqld/mysqld.pid
 #group mythtv
 start program = "/etc/init.d/mysql start"
 stop program = "/etc/init.d/mysql stop"
 if failed port 3306 then restart
