Apparently, although the program I was using was outputting in a .m4v format it was using an unsupported codec to do it.
The solution was to get a different free program called MPEG Streamclip (as well as a plugin for QuickTime called Perian). Easy install, and after which my problem was solved.
Hope that helps someone.
