Something to be careful about, everything what goes to file goes also to the
database, with default logging settings.
Cranking up the debuglevels blows your database up.

Set my debuglevel to "all" for 30 minutes, ended up with  a 7 GB MySQL DB.
Which can only be shrinked by dump/delete MySQL file/restore.

Worse was, that Mythtv does housekeeping jobs, cleaning the log table;
deleting millions of rows brings your system almost to a halt, stuttering
Had to truncate the logging table.

Use " --nodblog" when you don't intend to log to the DB.
I am on 0.27, it's fine for Job start/finish info's, for other stuff I can't
think it is valuable to log into a DB, therefor I can't understand setting
logging into the DB is enabled by default.
