I've recently upgraded to Tata Sky HD+ after purchasing a HDTV. I've been watching HD channels and for some reason the quality of Discovery HD channel is not that good. There is a lot of judder and the scenes with motion are very jerky (especially the scenes where the camera pans horizontally). I've been trying to fix my TV settings (thinking that it is a problem with TV settings) to reduce this effect, but not succeeded. I checked with TV showroom guys, and they said that it is the problem in transmission itself. Has anyone experienced this problem?
