Yammm runs as a Windows Service and will download meta data, artwork, rename folders, rename files and\or create playlists. Metadata can be any combination of dvdid.xml, mymovies.xml and\or XBMC nfo file. All meta information and artwork is provided via either
themoviedb.org or
thetvdb.com. If you haven't checked them out please do so and contribute where possible.
The primary reason for creating Yammm was meta manager that runs "headless" without ANY user interaction and used folder.jpg instead of custom artwork locations. This is important to me as I use various HTPC software depending on the situation and development. I also found that most did not match well. Yammm uses various checks other than the provider's score value
