Hi All, I'm having a big problem. I now have two Apple TV's (One 2nd Gen and 1 3rd Gen which we just got). The 2nd Gen has worked with no problems, and when we got the 3rd gen, we couldn't get it to work. After calling support, and then resetting my 2nd gen, and now my 2nd gen not working either, we have narrowed the problem down to ports not being open on my router/modem. I called Comcast/ Xfinity, and after 3 days, 5 disconnected calls, 8 calls, and 1 very unhappy customer, their only solution is that I return my Apple TV's or pay $40 ADDITIONAL PER MONTH, so that I may have these ports opened. That is absolutely absurd, so now, my only option is to open the ports myself. Please tell me that I am able to open certain ports, and if so, how do I do that. Please help!! PS: I have come to realise I have been spoiled with Apple's extraordinary customer service.
