Where's the difference to moving pictures? Is the benefit of a change worth the hassle.
My Films is focused on users that want to have control over their movie data and usually use external catalog software for that. If you only wish to scan and add movies to browse and play them in MediaPortal, you should use one of the really excellent plugins designed for exactly that purpose: Moving Pictures or the built in MP Videos. My Films is not intended as a replacement for these plugins.
