Hi
i bought the Q6f 49" at the weekend and i am having the same issue. i generally use a samsung surround sound system on everything but like you its driving me mad. Anything i watch or record on my tivo box has lag but not as bad as watching a dvd. I had to stop a movie as the sync was so far out it was so annoying
I have been told to adjust the audio sync. i have done this but no joy. The only way around it for me is to listen to everything through the tv. Not what i wanted at all
