mysqlcheck --user=root --pass=MediaPortal --auto-repair MPTVDB
before dropping the database could you just check it
Open up a command prompt (as admin if Vista / Win7)
navigate to MySQL Bin folder (is C:\\Program Files\\MySQL\\MySQL Server 5.1\\bin for me) and enter
Code:mysqlcheck --user=root --pass=MediaPortal --auto-repair MPTVDB
