I use Apple TV to stream my iTunes videos to my TV via home sharing. My iTunes library is on a NAS with the iTunes library set to NAS location. This works fine but after a while iTunes has reset the library to the default means I can no longer watch any of the files on the NAS. I can go back into iTunes preferences, point the library location to the NAS and everything works ok until iTunes decides to revert to the default file storage location again. I running iTunes on an old C2D mini with Snow leopard and teh laets version of iTunes. Any suggestions would be appreciated.
