Ok, so I've had my Apple TV for almost a year now. Downloaded the Take 2 update & t took me about 2 days to finally get logged into the iTunes store directly from the box. I just purchased a second refurbed ATV for my son & have been trying to get logged into the iTunes store for over a week with no luck. Any content purchased from iTunes will not play & comes up with the not Authorized message. Called Apple & they said that all they could suggest was Rebooting, Restoring or logging out & in a few times. I've even unauthorized & authorized my iTunes Mac a couple of times. None of which has worked. I'm using my .Mac account to login. On iTunes I use simply the first part of my .Mac email address without the @mac.com. I've tried signing in through his ATV with both my full .Mac email address as well as without the @mac.com. Why does my ATV work but not his? It's getting online & able to view trailers but no purchase ability & no playback. Has anyone gotten around this? Sorry if this is a double poast, I couldn't find a solution anywhere.
