I just bought an LG 37LC2D HDTV. I have noticed the audio delay on virtually ALL HD channels. I put it side by side with another HDTV I have to determine whether it was the signal or the TV, as I did not notice audio delay with the other HDTV (Vizio 42" Plasma). Sure enough, very noticeable lag with the LG audio. Only a fraction of a second lag but enough to be very annoying, especially for how much I paid for the TV. Based on my google searches of this LG model, I have seen too many other people with problems, so I will be taking it back and looking at other brands. Too bad though, because the picture is excellent (one of the best), and the sound quality is the best I have heard out of ant HDTV speakers.
