In chapter 13 on the DVD, (the scene where Kathryn is spying on Ceciel and Ronald), after Ceciel says "Peace out" Kathryn gets disgusted and turns the TV off. Keep watching the scene, they eventually pan around, concentrating on Sebastian and Kathryn gyrate on eachother... in the background, the TV's on.
I believe she either muted it or paused it. From that far away, I can't actually tell if there is anything moving on the screen, but I do know that, for the split second you see her with the remote onscreen, her thumb is in the middle of the remote.
