That seems to do it! I'll update the ticket.

There are a couple of other things that mythlink did that mythrename 
doesn't... :)

1) It doesn't delete old links for shows that have been deleted (I just 
add an rm * but it's pretty brutal)
2) I like to organize the links by making a folder for each show, and 
then just have the shows listed by title and date (again, I hacked mine, 
but not nicely)
