I'm lazy too...  I just check that there is an app running with that PID.

check process mythtv with pidfile /var/run/mythtv/mythbackend.pid
   start program = "/etc/init.d/mythtv-backend restart"
   stop program = "/etc/init.d/mythtv-backend stop"
   if 5 restarts within 5 cycles then timeout

I was going to do checks on myth port listening, etc.
There's already a separate check for mysql, which should be extended the
same way but I haven't got around to it yet.

check process mysqld with pidfile /var/run/mysqld/mysqld.pid
   start program = "/etc/init.d/mysql restart"
   stop program = "/etc/init.d/mysql stop"
   if 5 restarts within 5 cycles then timeout

Something like this:
   if failed host 127.0.0.1 port 3306 type tcp then restart
   if failed host 127.0.0.1 port 3306 type udp then restart

Yeah - its just a "/etc/init.d/monit stop" , or you could tell monit to
   monit unmonitor mythtv-backend
do stuff
   monit monitor mythtv-backend
