Okay, I just bought an appletv. the only other thing I own is an iMac G5 connected to my cable modem. Is there anything else i need? Only way I can get Apple TV to appear under devices is if I connect it to imac via ethernet wire. I got impression appletv and imac G5 both had something built-in to them so my music could be streamed to apple tv. Is this correct? if not, what else do i need to buy? Also i'm not big on wireless stuff. I still feel data is transfered quicker and smoother via wires. Is it possible to have internet plugged into back of imac and also have apple tv plugged into imac at same time? Any help would be appreciated.
