Got it installed today. Mostly it looks great - got a Sony kdl-40w4500. I would say that SD is only reasonable (for the most part - some channels are better than others). On HD, BBC is fine, Sky Sports is absolutely excellent, which is what I was praying for. I find that the difference between SD and 1080i is vast, Also, the difference between 1080p and 1080i through Sky HD is smaller than I thought. The former through blu-ray is obviously superior although it's not as vast as the difference between SD and 1080i. Also, the settings on the w4500 requires quite a bit of toying with before you get a perfect picture and the settings are quite different between different channels, which means it's it's pointless to post a set of generic perfect settings. Have had the TV for 6 weeks and was greatly relieved that Sky HD provides a pretty decent picture.
