Totally let down by my new Apple TV 4th gen. Turns out that Apple TV 2nd, 3rd, and 4th generation only cache about 100 photos from your iTunes photo home sharing library and then only randomizes those few photos for screensaver and slideshow...duplicates constantly. This problem bug is super annoyingly oblivious in Floating screensaver mode. 1st generation Apple TV is the only unit that truly randomizes all your iTunes home sharing photos because it synced all photo's from your iTunes file to its hard drive for use with screensaver. This is particularly insanely stupid given the new 4th gen Apple TV has a solid state drive with 32gb or 64gb of space. An easy software modification could allow the entire home sharing iTunes photo library file to be loaded onto the 4th gen's hard drive and the screensaver program could then truly utilize and randomize all your home photos...just like the 1st gen Apple TV (which has the world's all time best screensaver)...but alas, per Apple Customer Care, home sharing of my photos for the screensaver is limited to about 100 photo's total per screensaver session as this is all the unit pulls into its cache from my iTunes home computer library photo file. I hope some engineer at Apple will see how stupid the new screensaver operates with home sharing iTunes photo's. I only have about 2000 photos but I know some people have tens of thousands. This is the modern digital age where we all have tonnes and tonnes and tonnes of photos...how is Apple not allowing us to display them in the same awesome manner as the 1st gen Apple TV...I am truly baffled by this one. Guess I'm returning my Apple TV 4th gen tomorrow (after I was told by Apple Customer Care before purchasing it that it would randomize and display all my home sharing photos in screensaver...wrong! Only about 100-150 per screensaver session). Side Note: I do understand that playing your screensaver photos from the iCloud is supposed to then utilize all photos for random display on screensaver although I can not confirm this to be true or false. The problem I am noting is specifically in regards to home network sharing of photos from a home computer with iTunes for use with the Apple TV 4th gen screensaver feature. Any help or suggestions with work arounds and/or third party screensaver apps, etc would be greatly appreciated.
