I'm getting audio lag (only slightly, but noticable, and spoils the new 3D experience). It only happens when I watch a 3D Blu-ray (Captain America) I have the following equipment. Samsung UE46D7000 - 3D TV Samsung BD-D6500 - 3D Blu-ray player Samsung HW-D570 - Sound Bar The Blu-ray player is connected to the TV in Port 3 using a fast (and expensive) HDMI lead. The Sound Bar is connected to the TV using an HDMI lead in Port 2 (ARC) and also using an optical lead. I have tried various audio delay settings, but these are now all on Zero. Both the TV and Blu-ray player have the latest firmware installed. Any advice on this matter would be greatly appreciated. Thanks.
