At first I noticed the lip sync issue with OTA which was not a problem as I only used it during thunderstorms when the satellite was down.
A few months in, I noticed it on Voom satellite and searched the web and noticed it was a known problem. Reported it to Samsung and the immediately knew what I was talking about and put me in touch with the local tech. Local tech replaced a board set (took him two trips to do it) and it fixed the satellite input but not OTA. Let it slide.
Voom went out of business and I switched to TW Cable. Problem reappeared. When initially wired up to HD Cable STB, the cable guy couldn't use the DVI input and eventually connected the HD Cable STB to Component 3.
Called Samsung and reported problem again and referred to same local tech who wanted to come out and replace the same board. I called them back and they agreed to come out later this week to tweak some settings instead.
In the mean time I bought an HD Upconverting DVD with a DVI output and moved the HD Cable to Component 1 and noticed that lip sync issue was better, but not completely eliminated.
I'm going to let the local tech come out this week and make his tweaks to see if they make a difference.
I too would hate that idea that such an expensive set with such a great picture has an inherent design problem with audio syncronization.

I was told by CC & BestBuy salesmen that the problem was gone with the HLP series, but it was not. I bet you were told it was solved with the HLNs too!
Samsung keeps saying it is solved with each new model year, but it just gets a little better. Eventually they will not be lying about it when they either get faster video processing chips, or tame the extensive video processing (I think over processing). AT the rate they seem to be progressing, they should solve the problem in about 4 model years.
Samsung told me that less than 1% of the TVs have lip-sync problems, but they also said almost all their customers just use the TV's internal speakers, so take that 1% number with a grain of salt.
