Like the title says. for example, I’ve got the movie ‘mamma mia’ in a folder named ‘mamma mia (2008)’ and the file name is the same as the folder name. Media player won’t produce cover art for it and when I choose to reload metatdata, nothing happens.
I’d leave off the ! and name the file “Mamma Mia The Movie” w/o quotes. ATVFlash scrapes meta data for movies from http://www.themoviedb.org/, or in this case http://www.themoviedb.org/movie/11631-mamma-mia. Match what they show and it should pick it up, I’ve found removing special characters (anything that’s not a number or letter) provides better results.
