Your Apple TV is not authorized to play this content

I get this message ('Your Apple TV is not authorized to play this content') when I try to play any movie or TV show that I bought on my Mac Mini which I try and play via Apple TV. I have tried to de-authorize and authorize my account, rebooted the TV, and even rebooted the Mini that the media is on, but no luck.

1. I am able to play the SAME content on another Mac via homesharing.
2. If I purchase a new TV episode on my Mini then it plays fine on my ATV. So it looks like the problem is with content that I purchased before I had the ATV.


Any suggestions on what I could do?

Download Handbrake, and convert the media to "universal" or "AppleTV."

I have this problem on my ATV 1 every so often. I have to re-sync my Library and it works fine afterwards. Since the ATV 2 interfaces with iTunes and your Mac differently I suspect that won't work.
