Hello, New here so please bear with me Bought my PVR in Feb & it worked perfectly until yesterday. The picture now stutters on all channels, I checked the Signal Quality & it was constantly fluctuating between 40% and 100% (signal strength is 81%). I powered the Humax off for a while and restarted. Initially the picture is perfect for a few mins then the fluctuation starts again. It is still the same now. Can anyone help or is this a case of sending the box back? Many thanks.
