Must be lots of folk using Sky HD with systems better than mine. Watched Cowboys and Aliens yesterday and found the soundtrack excellent. Other programmes can seem way off quality. I appreciate that older recordings may not be great but wondering about other channels - are some channels better than others or does it vary from programme to programme? Are the American offerings worse than UK? Are fims better than TV programmes? I am thinking about DD - balance between channels, clarity of sound etc. I guess the picture varies too.
