After the latest os update, when I'm air playing videos from quicktime, it's a hit or miss to if it'll actually play on my atv. It opens up on the atv, but it mostly just won't play, however quicktime is still showing the playtime counting. I've reset everything, I haven't changed any network settings, so I doubt it's that. I'm just not sure what to do, but I'm so annoyed because airplay is a big reason why I bought the atv4 =[
