I have a ATV 3; Itunes has the latest update and my Mac is running Version 10.8.3. My network is all hardwired. If I play a movie on my ATV through iTunes, it plays perfectly. If I use Netflix; it plays perfectly. However, if I try to stream it via Airplay; I get major pixillation on my Tv. I have tried various players; however; the one I use the majority of the time is VLC. The pixillation problem is the same with all the players. What could I be doing wrong???
