I have a iMac G5 with built in airport extreme and I want to connect to my Apple TV wirelessly. I also have DSL that is connected to my mac ethernet port. Can someone please tell me how to wirelessly connect my ATV. I can create a wireless connection from my DSL modem to my ATV to access internet content on the ATV, but I don't see the ATV in my itunes device list (I do have the 'Look for Apple TV's' box checked). Any help would be much appreciated.
