There's a good explanation of Storage Groups in MythVideo in the wiki

http://www.mythtv.org/wiki/Mythvideo#Storage_Groups

<http://www.mythtv.org/wiki/Mythvideo#Storage_Groups>The simple answer is,
blank out the path in the frontend configuration and MythVideo will only use
the Storage Group folder defined on the backend (and thus simplifying the
frontend configuration in the long run)
