The title says it all, but to give a little more detail.
What I want to be able to do is to sit on my sofa, and select music via my iPhone or iPad and then that music is played on my TV (which is connected to my Hi-Fi).
Is this possible? I really want to use the native music selection from the phone.
I don't really want to buy AppleTV, as I already have enough computers in the house in theory to make this kind of system possible.
Does anyone know how I can make this work?
