Yes. All you need to do is to install VLC and organize your files in a given folder structure. It's also possible to add covers then. If, for example, you want to add the file MyMovie.avi, the folder structure should look like this:
Title of my movie/VIDEO_TS/MyMovie.avi Title of my movie/File with Cover.jpgYou can add movies that are split up into several files the same way. The folder structure then looks like this:
Title of my movie/VIDEO_TS/MyMovie part 1.avi Title of my movie/VIDEO_TS/MyMovie part 2.avi Title of my movie/VIDEO_TS/MyMovie part 3.avi Title of my movie/File with Cover.jpg
The names of the movie- and coverfiles are freely choosable - you only need to make sure the suffix fits the format of the file. Supported formats for cover files include JPEG, PNG and GIF.
In Remote Buddy's menu, you can then start playback of your movies complete with existing covers in the context menu of the VLC Behaviour.
