Hi guys , I am thinking about buying the new Apple TV. The thing is, I got a surround sound connected in my iMac and my tv is a little far from it. I want to play the same music both in my home theater connected in my TV and in my sorround connected in my iMac AT THE SAME TIME. Is that possible ? I mean, once I play it on my itunes it start streaming to my apple tv . Is that possible ? Thank you!
