Strange problem started happening in the last week or two, after years of mostly hassle-free operation of my Apple TV(s). Now, when I turn on my system after a period of non-use, I am able to see the Apple TV main menu as if it is connected to my wireless network, but selecting any app (say, Movies), will lead to the "Connecting to iTunes Store" screen with the waiting animation indefinitely. Once I go into settings and restart the Apple TV, everything works just fine -- snappy, with instant access to apps and content. I now have to restart the Apple TV every single time I want to use it. Never seen this before...any ideas?
