I struggled to get through Pearl Harbor on a brand new Samsung 3D blu ray player sending HDMI to a Yamaha RXV-675 to a new Panasonic 65" plasma tv. Lip sync made the movie unwatchable. My test scene was about two hours into the movie when Roosevelt was addressing his advisors about the attack on Pearl Harbor. Easily a 1/4 to 1/2 second lip sync issue. Yes my Yamaha has a lip sync adjust feature but why? Obviously this is a common enough issue that it must be compensated for but is the root of the problem?
I can't just go with an adjustment at the receiver level because Swordfish, the title I have on right now, plays back fine with no lip sync adjustment.
To make matters more confusing, I plugged in my three year old Panasonic Blu-ray player and tried that same scene from Pearl Harbor. It played back just fine. I purchased and have already returned a new Sony 3D player as it performs as poorly as the Samsung does. I may try a Panasonic tomorrow but since the 3D models are all sold out I'll have to get a 2D unit. I may do that as lip sync issues are, for one, annoying, but more importantly, shouldn't be here in the first place. My old Panasonic proves this.
So what is it that causes this issue? I have heard it is often the tv. The sound and picture enter the receiver and are output to the tv and speakers in a setup like mine. Supposedly there is enough processing being done by the tv that results in a slight delay between the time the image is received and the time it is displayed. This would make sense but in my case one player does it and one does not. This eliminates the TV, receiver and also the BD title itself. What is more confusing is that this Samsung plays some movies okay and others not okay. Both Swordfish and Pearl Harbor are older movies so it isn't like old vs. new comes into play.
Anyone know what is really going on?
