A neat feature of the Apple TV app is that playback continues in the upper right corner of the screen when you hit the back button while watching live tv or dvr content. You are then able to view the channel guide.
It goes half a step further by allowing you to access the sidebar menu items but as soon as you move up or down playback stops.
It seems like playback should continue until you select a specific library item or at least it would be really cool if it did.
