Donutlover -- Got it! The link you provided gave me the solution.
Go to System (gear icon)
Go to Media
Under Library (left column), go to Videos...
Right-click (content menu) on "Movies" (or whatever your movie folder is called)
Select "Change content"
Change "Choose information provider" to "The Movie Database Python" and click Ok.
It asked me if I wanted it to rescan the entire content, and I opted not to.
Thanks for the help,
Richard
