Will AirPort Express allow me to play music from the iPod app through my amplifier (via an audio cable connected between AirPort Express and the RCA inputs)? Does it appear as another output option with AppleTV and the iPad? While I am asking questions, how do AirPort Express and AppleTV fit together? I am not just being lazy asking on this forum, I don't think that the Apple web site explains things clearly enough. I have already bought AppleTV for this (and other purposes) only to find that it doesn't quite do what I want, on multiple counts. I don't want to spend more money on AirPort Express, only to be disappointed again.
