Shut down all backends/frontends and delete the directory from the 
storage group using mythtv-setup.  Doing so will not alter the database, 
so Myth will think all the recordings are still there.  Then, restart 
the backend(s) and frontend(s) and you can manually scroll through the 
list and delete any missing file using the action menu (hit 'I', select 
Delete, then confirm that you want to delete it even though the file 
doesn't exist).  Or, you can try myth_find_orphans.pl .
