I recently purchased a new 3rd Gen Apple TV. Everything seems to be set up fine. Home Sharing is working. I can access the apps, itunes, and my photos (photo stream or over home sharing). Airplay is working great. However, when I try to use the screensavers or slideshow settings, the only one that will work is "Floating". If I set the theme to anything other than Floating, I just get a black screen. Note that this is the case whether I'm using my own photos or any of the built in photo libraries (e.g. Nat Geo, Animals, etc). Is anyone else having this issue? Also, when using my own photos, it seems to just repeat the same 100 or so images. Is there anyway to get the screensaver to pull from my full photo library (~5,000 images)? My PC is on Windows 7.
