Same issue here. Netflix slows to a near literal frame-by-frame crawl and only restarting AppleTV temporarily fixes is. It seemed to start within the last few weeks. Also, I've noticed that I cannot alter "My List" on Netflix at all. I cannot remove or add anything to it. We have two Profiles and neither one's My List works as expected. I'm wondering if that's some conflict between AppleTV accounts and Netflix Profiles. I dunno.
