Q: I recently bought an Apple AirPort Express and set up a set of speakers to give me AirPlay capability. It works perfectly from my iPhone, my iPad and from iTunes on my Windows 7 PC. Well, almost perfectly. Last night I rented an iTunes movie to watch on my PC and when I started the movie I realized I couldn’t select my AirPlay speakers. A quick Google search told me it is apparently not possible. Do you know if this is true? It seems crazy…
