Sorry for the very late reply but no, this is not currently possible. In the future we plan to add support via UPC scanning of DVD barcodes, as well as bulk importation based on some sort of text file with a list of movies.
this is exactly what I am looking to do as well. With more than 200 movies, it would be a real pain to have to put the disc in each time I wanted to add a movie. Between that and Moving Pictures telling me where it is located (the bulk CD cases, or which closet, and so on) this would be great.
Also an ability to add search by genre or actor and such would be amazing!
well, you could just create dummy-files for all the movies. Make a small video-clip with just the text "look in your DVD-cabinet" for a couple of seconds.
Put it in a folder called "Dummy DVD-movies" and add this folder to the importer of Moving Pictures. Then name the clip "The Dark Knight (2009).mpg", make a copy, name it "Public Enemies (2009)", copy it... repeat, repeat, repeat.
It is a bit tedious, but it would get the job done. I don't know if it is somehow possible, with the new features, to somehow show within MP-gui that the movies is located within "Dummy DVD-movies"-folder, so you would know to find it, before you actually press play.
