My first guess is permissions and ownership of these new directories.

When you use mythtv-setup to adjust StorageGroups you should get a 
message when you exit mythtv-setup if there is a problem writing to 
Storage Group directories.

Is there anything in the mythbackend.log about Storagegroups and not 
being able to read/write ?

The ownership and permissions I use are
All directories should be owned by mythtv.mythtv
permissions required on the directories are u=rwx,g=rwxs,o=rx

Something like these commands should do it:

sudo chown -R mythtv.mythtv /media/[myname]/Storage/myth
sudo chmod -R  u=rwx,g=rwxs,o=rx /media/[myname]/Storage/myth

As a second guess, there was an old problem with mounting to /media
