Hi all. I wondered if any other plasma users are having the same problem as me. When watching sky news there is text constantly scrolling across the bottom of the screen,half of the time it scrolls fine but will then start to judder and vibrate for up to ten seconds before reverting to smooth scrolling. In WHF review this set actually gets a mention for handling scrolling text well so what gives? I have sky HD via QED HDMI and would be very grateful for any experiences shared.
