When it rains the freeview channels become unwatchable through our Youview+ box. Signal strength is at approx 98% but the quality is down around 58%. If the aerial is plugged directly into the TV the picture is perfect. We had a new aerial fitted in January with new cable. Why is the Youview+ box so poor compared to the tuner built into the TV? Surely there is a problem with the box. The box is only just over a year old and has been doing this for several months. It's only because we've had good weather the last 6 weeks or so that I haven't got round to doing anything about it. Now it's raining again it's brought it back to the fore.
