Ok I've been reading up a bit on this lip sync issue caused by the image processing in the display. I've seen a number of posts where people claim that this cable or black box has helped with the lip sync. TBH I can't see how this would help! Do these cables really help? if so how? Also am I right in thinking that the Panasonic Panels are especially susceptible to this? Really how much of an issue is it? I'm currently thinking of getting a Panasonic 37 / 42" panel if I have to buy a whole new amp just to add a sound delay (which isn't a real fix anyway) I'm just not going to bother!
