I think (I'm a noob here too)
what Marcos, Michael and Graeme want to say, is

- first declare Interfaces, inheriting from those you want,

(namely IVideoFile, IAudioFile with appropriate get/set methods)

- then make IFile inherit from the above and from IUnknown, not the other way round

(hope I got that right /)  )
