Hello, as a secondary purpose, I would maybe stream from some of ATVs video channels. However, music from itunes on PC to a/v receiver is the main goal with the best possible audio quality. I was looking at a Roku box too. Just seemed easier for using an apple tv to stream from apple itunes. User friendy as well. Apple airport express also seems good but its also a router and I already have one, so not sure if they woul play nice together.
