"If that doesn't work, try adding the library to iTunes so it will rebuild tagging info. Usually I delete everything in iTunes folder before adding the library."
That's exactly the problem I had with iTunes. It takes matters into its own hands, and starts retagging everything. I don't see why you would want it to do something like that.
He configured LMS to use iTunes ... I never had problems with iTunes or LMS. BTW I prefer LMS over JRiver, PS Audio, MinimServer ... for SQ and reliability. Too bad they got bought out.
My guess is index needs updating in LMS.
