If you are streaming rentals from the iTunes store, watching YouTube, etc. then yes as the other poster stated. If you are streaming content from a computer on your own iTunes library on your local network, then no.
Garbled sound AppleTV2. I think I have overwhelmed my AppleTV2. Latest firmware update, reset, ran perfectly, on all day, viewing photos, streaming itunes songs from my macbook pro, watching utube content, etc. I love it EXCEPT... after about 12 hours the sound got garbled. Things still play but barely recognizable as audio. All sound, even directly from the AppleTV was garbled. Reset the AppleTV and the audio returned to normal. Should I be concerned? Is there a setting or something I am doing to cause this problem?
