Hi all...My tv is HD Ready (Panny TH42PX80) and have just had SKY HD installed!! But my HD ics all seem a little juddery. The box is set to the default 1080i and I am wondering if there might be a better setting since I think the Panny upscales to 1080p and then down to 720p (I think). Am still experimenting but would be bgrateful if anyone had some set-up or 'refining' pointers. Thank you.
