[mythtvnz] Adding a HDD with existing myth directories

[Noel & Di]

Thanks Corrin
I have set up the new box, and it works perfect...will have to make an 
LVM partition.  Export/import will take a while - I have 200Gb of 
recordings.
Next weekends project I guess.  To many sceduled recordings mid-week & I 
don't like to upset the WAF.
