[mythtv-users] MYSQL ---> ERROR 1016 when attempting mythconverg backup

[Ben]

Hello,
       I'm trying to upgrade to svn from the Debian packages (no longer 
maintained).  So far I have not actually removed any Debian packages, 
nor have I installed any of the svn build. However I am unable to backup 
the database, with the following error:


-----><-----------------------------------------------------------------------------------------------------------
mythtv at myth:~/backup_myth$ mysqldump -u mythtv -p mythconverg -c > 
mythtv_backup.sql
Enter password:
mysqldump: Got error: 1016: Can't open file: 'oldprogram.MYI' (errno: 
145) when using LOCK TABLES
---------------------------------------------------------------------------------------------------><---------


Can anyone help?  How do I repair the database?

Thanks
Ben
