have had sky for years upgraded to sky + then sky +hd without paying for the hd channels, just noticed the past while when watching movies on the ordinary channels ie sky movies that the picture is not as good as it was, reaks up a liitle, have a large tv 50" samsung but this is only been happen the past 6 months. it was good before. Think sky is sending a less singal down so the picture is bad and you have to pay the extra 10 for hd . what do you think????
