The situation I have at the moment is that I have a laptop connected to a projector. I need to connect the laptop to the speakers for the sound to come out. The speakers are next to the projector screen which is about 10m away from the laptop. The laptop is a Sony Vaio, but I think a Powerbook may be used also. What I'm looking at is the Airtunes, as this would be a hell of a lot easier and tidier to connect the laptop to the speakers. The problem however being that I do not want to just play songs from iTunes through the speakers, I would like to be able to play the sound from DVD files and video files on the computer. Is this possible? Either with Airtunes or something similar I do not mind?
