Right.  The confusion here is (once again) that a Storage Group is just 
a name for a list of directories.  Too many people think that "Storage 
Group" means directory.  It does not.  :)

http://www.gossamer-threads.com/lists/mythtv/users/516083#516083

has an example of Storage Groups and directories.

So, basically, you need one or more Storage Groups, such that those 
Storage Groups contain directories, which provide access to multiple 
file systems, ideally such that you have as many file systems available 
as you will do concurrent recordings.  So, if you're doing 20 concurrent 
recordings, you'd ideally have 20 file systems available within the 
Storage Group(s) you use, which means you'd have at least 20 directories 
specified within the one Storage Group.
