Until yesterday I was only running Roku devices in my house, but I got an AppleTV HD recently and really like it so far, but I was showing my SO the new selection of live-tv and found scrolling down the list was really frustrating with swiping action.
So this could be a problem with the app or my lack of knowledge of my new player. I found that not only did swiping down not take me very far down the list, but it would often pop me back up to the top for no reason, which stinks because all I like are the music video channels at the veeeeery bottom.
