Anyone seeing the photo sharing lag times? I'm able to show the first photo after initiating airplay of a photo on my iphone, but flipping through the album seldom works well. It is extremely laggy. LAN in my home is very good - dual band airport extreme with 5Ghz N and 2.4Ghz running b/g/n. Connections are all good, movies run to two aTV 2s just fine, as do photos when shared normally via home sharing. I want to like Airplay, but I have to say that it's been disappointing so far.
