That’s because the TV Wonder 650 doesn’t support concurrent dual tuner functionality of its analog / digital components. There is no working around this very real hardware design limitation. For concurrent dual tuner functionality simply add another tuner and designate tuner priority accordingly to avoid using both tuners on the TV Wonder 650 simultaneously.
