I was watching Pirates of the Caribbean last night in HD(recorded on Christmas Eve). Half way through the sound started to break up and the picture was freezing. My son then told me he had the same dvd, so we played that. The picture was very good from his disc, but the sound through my home cinema was awesome compared to the Sky HD version I was watching. I have HDMI cable from home cinema to tv, and HDMI cable from Sky HD box to tv, and an optical cable from HD box to home cinema, should there be that much difference in sound quality?
