Screensaver Doesn't Update Photos from iPhoto Album
I can't seem to get the screensaver in AppleTV 3rd gen to update the photos it shows during its screensaver.
In other words, it seems to have cached a certain amount of the photos from the selected iPhoto album and then rarely updates that cache.
I tried restarting AppleTV multiple times while ensuring that my Mac running iPhoto is awake and accessible on the network. I've also removed certain photos from the selected iPhoto album, but more-or-less the same photos keep showing up in the screensaver.
Any ideas on what's wrong and how to get AppleTV to better do what it's supposed to with choosing screensaver photos?
