Apologies for what is likely an obvious newbie question, but I've searched and not found what I'm after. Is there a way to control audio input to my home entertainment system from my mac, remotely using some sort of wifi connection. I have a pretty basic home theater system built around a denon receiver. Multiple Macs running 10.5.8 House is wired with airport express. and already plug my iPod into the sound system via a base and y cable. Is there a way to control the music stream remotely, from one of the Macs in the household? Is this something that the AppleTV can do for me?
