Do a full scan.

The approach I would use is to back up the database ( 
http://www.mythtv.org/wiki/Database_Backup_and_Restore ), then try the 
video sources portion of 
http://www.gossamer-threads.com/lists/mythtv/users/264034#264034 .  If 
that doesn't work, you can restore your backup and be back where you were.
