If you're getting the following error in your mythbackend log:

	Driver error was [2/145]:
	QMYSQL3: Unable to execute query
	Database error was:
	Table './mythconverg/mythlog' is marked as crashed and should be repaired

And you've tried to repair the mythlog table with:

	mysql> repair table mythlog;

	+---------------------+--------+----------+-----------------------------+
	| Table               | Op     | Msg_type | Msg_text                    |
	+---------------------+--------+----------+-----------------------------+
	| mythconverg.mythlog | repair | status   | Table is already up to date | 
	+---------------------+--------+----------+-----------------------------+
	1 row in set, 2 warnings (0.00 sec)


..but mythtv still reports an error, fix it with myisamchk --recover mythlog:

	# cd /var/lib/mysql/mythconverg
	# myisamchk --recover mythlog
		- recovering (with sort) MyISAM-table 'mythlog'
		Data records: 7
		- Fixing index 1
		Data records: 5


Those pesky mythtv mysql mythlog errors will be a thing of the past... :D
