Thanks. I changed the iTunes Music Folder Location (under the Advanced section of the iTunes Preferences) to my NV+ music location. I should add at this point that my computers are Mac’s.
Unfortunately, even after a reboot and restart of iTunes the program still looks in the local hard drive (C: ) library for the Music library, though I can still see and stream from the NV+ which is still listed as iTunes Server in the Shared section of iTunes.
So, I am none the wiser right now. The question remains, to access the library with any decent functionality, do I have to copy my music library onto all of my computers separately? If that is the case, it kind of defeats the excessive copyright controls which do not allow sync’ing from a remote library.
