G'day, I have an imac and airport express which I use to stream music from itunes to my stereo system in the kids room which works perfectly. I recently bought a Yamaha RX-V3900 receiver for my home theatre room which has an ethernet connection at the back. I have hard wired the av receiver to my router and I have got a connection as I can hear internet radio stations through the receiver. What I cant figure out is how to stream music from itunes to the receiver in a similar manner to the way I do with airport express. I was hoping this would be possible as I dont want to have to purchase another airport express if I can help it. Thanks.
