[mythtvnz] Migrating storage groups from 0.21 to 0.22

[Noel & Di]

Hi
I have recently upgraded my Myth box from Ubuntu 7.10 to 9.10
I used a 16 GB CF card in the finish as the system drive, and have 7.10 
intact on the original system drive in case of emergency.  Handy to 
maintain the WAF when I fiddle.
The myth0.21 system has storage groups set up on a separate HDD.  On 
9.10 I finally got past the DiSeq page and set up the LNB (by using a 
right arrow then enter of all things on the Not Connected message).  The 
next hurdle is to get the machine to list the storage group contents for 
Recordings and Video.  The storage drive is mounted OK, the music files 
are visible & play, same the pictures, but when trying to browse 
recordings or video the system reports no files. Any ideas?
