Just picked up a new Sammy 40" LCD. Its really good so far apart from one tiny problem. SKY! Its connected via RGB scart as it doesnt have any other connection apart from the old composite i think. Im having lag problems. The sound sometimes is in front of the picture. Maybe by a good half a second. Is there anything i can do to correct this? Ive had a look around the samsung menus and such, but cant seem to locate anything?
