We use it over XBL and the biggest problem we face (outside of the search/lack of content issue) is that if someone so much as accidentally knicks the controller, drops it on the ground or accidentally presses a button while moving it, it makes a transition without verification. Most of the time, the button accidentally pressed either starts the movie from the beginning or begins rewinding/forwarding the content. This is pretty terrible UX to begin with, but then on the UI side, there's no marker where that action started taking place or an "undo" function. This happens at least once every time we use the XBOX version, so we've taken to unplugging the controller entirely to avoid it.
