Thanks
Each collection of Music is in a separate network share, I.e.
\\WHS-SRV\Flac
\\WHS-SRV\Wife
I see with the customize view I can select a file path which I think is what I'm after.
What I really need is for each view to be selectable separately in Theatre View however I always seem to see Music from both locations in there.
A few more pointers and I'm sure I'll get there!
Cheers
