apple tv screen saver reverting to National Geographic
As of May 3, my TV is reverting to showing pictures from the National Geographic set instead of the selected album on my local network computer. If I return to preferences, it still lists the correct album from the computer, and selecting Preview begins a slideshow from the correct album. The next time based activation of screensaver then shows the correct album for about 2 minutes, then it fades to black momentarily and begins a slideshow from the Nat Geo photos. Subsequent screensaver activations are then all Nat Geo. Unless I repeat the procedure with preferences.
The computer in question has had the Yosemite update including the Photos app installed (on release day), but this activity did not begin until yesterday, many days later. That computer has not been migrated to using Photos, is still using iPhoto, and no changes were made in iTunes.
Given my parents are having a very similar issue with just showing a library sideshow on one of their macs from the Photos library on that Mac, I suspect this is is all related to the rollout of Photos and it's integration with other devices, and I'll be waiting for Apple to get it together.
Any other suggestions?
