You or em28xx is wrong. Neither are wrong. In some cases the call needs to be intercepted by the frontend in order to disable its TS output. In other cases it needs to be intercepted by the bridge to control a MUX chip which dictates which demodulator's TS output to route from (typically by toggling a GPIO). Devin -- Devin J.
