Hello, I bought an AppleTV last Friday and I have a few questions. I have three accounts for three different countries. If I register the AppleTV under one account, will it still work with the other three? My subwoofer isn't working with any video with DD5.1 that I've bought or rented from iTunes. The subwoofer is working fine with my DVD player. Does anyone know what might be causing this? Several movies are displayed in the "TOP MOVIES" section as being iTunes Extras, but when I go to view each page only some of the movies are marked as iTunes Extras in the top right corner. Why is this? Cheers.
