I am using a HDR-FOX T2, the Ariel wire comes into the box and then onwards to the TV, The box is working correctly , recording ok and when we have two recordings scheduled and want to watch a third channel we change the TV setting and watch on the TV. The problem starts when we turn off the Humax box and try to use the TV alone as a source for the radio, we have no signal unless the Humax box is turned on. Is this correct, the old Sky box did not work like this ???
