Received my 2nd gen ATV yesterday, and successfully setup home sharing with iTunes on my mac, along with photo sharing. I really like the photo screensaver capability of the ATV, and set it up to use my entire iPhoto library with "Floating". However, every time the screensaver starts it shows a bunch of pictures from 10 years ago (the oldest stuff in my iPhoto library). I don't mind seeing these pictures, but I'd prefer to get the photos in random order and not "oldest first". I can't seem to find a "photo shuffle" preference, am I missing something?
