What's the advantage of using storage groups?  I am running svn and have noted that 
storage groups are much more expanded then in 0.21 -- but I really don't get 
their advantage over using something like symlinks....  (expect the scenario where
you are saving a tv series to a particular folder, but that requires editing myth-setup
every time you want to add a new series (right?))
