I am having issues with picture distortion mainly on bbc 1, bbc 2 and ITV (though other channels too) and tends to be around the same time of day 5-8pm (other times too). I have checked the connections inside and outside. I have rebooted box. And have connected to Virgin Media Now through network settings. I have also checked it’s not an issue with the tv channels by checkingbthe reception via aerial and it is fine. I have tried contacting via twitter but have had no reply. If anyone has any ideas?
