That's interesting. For example, I know the HLN437W and HLN4365W are supposed to have the same internals, but the 4365 did list for less money. I wonder if it used some less expensive components? Does anyone know if the XX7W tv's are more/less prone to this problem than the XX65W line?
I have the 437W which has the Faroudja trademark emblazoned on it, and I have the problem with some signals (but not others). My audio sync issues with 480i reception from cable were worse before I added a distribution amp to my home cable setup. My picture got better, AND the degree of a/v out-of-sync became less. Mostly.
In my opinion the amount of video delay is dependent on how much processing/clean-up the TV (possibly including the Faroudja chip) decides it needs to do, which can vary from signal to signal, and probably from time to time while watching a single source, as well. I wonder if Sammy's engineers were blindsided, in part, by variations in processing delay by the Faroudja chip.
I also have the HD931 DVD player, which has the Faroudja chip as well, attached to my TV's DVI input, and I see varying amounts of delay on DVDs -- including some that play in perfect sync on my years-old Sony DVD player and XBR CRT set.
Things I have hooked up to the component inputs on my TV seem to be the least of my worries (Moto 5200 HD cable box, ReplayTV). I have the cable box set to output 720p no matter what, and that seems to minimize a/v sync problems when I'm watcing HD programming. (I watch analog cable directly from the TV, since the PQ is better than when viewing analog channels through the 5200).
