The 622 is a dual tuner dvr and can work in one of two modes. Single mode while allowing pip also limits all tvs to view the same live/recorded show at the same time. Dual mode loses the pip feature but allows two seperate views on tv's hooked to it. Depending on how your daughters tv is connect, she can either have the same view as main tv or seperate viewing. With no ota, she could watch what is being recorded on either tuner or previously recorded program.
