I want to connect the output of my laptop to a projector and beam a movie on the wall.

The movie has video and audio, but I would like to be able to play different audio tracks while the video is playing.

Is this possible?

You can use VLC to remove the default audio (Media -> Convert/Save...; Check Video and Keep original video track in the profile options, uncheck Audio. Use a new profile to leave other settings intact!).

VLC can open additional audio at Media -> Advanced Open File... -> Show more options.

Download: VLC media player

The menu labels seem to have changed. Now it's Media > Open multiple files. Pick the video file in the normal file selection, then tick "show more options" and "play another media sychronously". In the browse input that appears, select the audio to play. You can then play or save this merged media. Image showing the window: (from VLC 2.2.1). – Kat Sep 3 '15 at 21:54
