You could add several methods:

QStringList StorageGroup::GetAllFiles(bool descendIntoSubDirs = false)
    - get list of all files in the current SG's directories

QStringList StorageGroup::GetDirFiles(QString dir)
    - get list of all files in the specified dir

QStringList StorageGroup::GetDirSubDirs(QString dir)
    - get list of all subdirs in the specified dir

These would let you traverse the tree(s) in a GUI and would come in
handy for other things as well.  If you only store the actual filename
in the DB, then the user can move files around without needing to update
the DB.  This makes MythVideo as flexible as the main MythTV
functionality regarding file locations.

mythgallery could take advantage of code like this as well for its
browser.
