Howdy,

I have a 47PFL7403D screen with HD Natural Motion.

My problem is i bought a blue ray player hooked the picture up via HDMI to my tv and hooked the blue ray audio up via optical fibre cable direct to my amp. Sounds great and looks terrific except for the fact that the sound is approx 1/4 sec ahead of the picture.


After hours of tinkering I found that having the HD natural motion on is the cause of the sync issue (must be due to the processing of the picture).

If I turn the HD natural motion off the picture and audio is perfectly in sync but this deteriorates the picture quality, which defeats the purpose of the blue ray player.


So then i decided to go and buy a digital coax and run it straight from the tv to the amp, this worked but sound is average as the tv must not be able to produce dolby digital from its digital audio processor.


So I am stuck at the moment, do I leave natural motion off and have full dolby sound thru my amp, or do I have it on and have avergae sound via the tv to my amp.

I know this is a long winded story but I am a but frustrated and it would be good to know if others out there have experienced the same problems and how have they overcome it

I do not have experience with this specific scenario. I can tell you that when you use display speakers on audio coming from one source and video from another, there are times when the audio source has to be delayed. This is due to the fact that, as you stated, the video source takes time to assemble on the display. Does your receiver with the optical input have any time adjustment capability? You can't expect the audio to match the video because the display has nothing to reference timing for the sound. You have a Blue Ray player sending information over HDMI for video, and an optical out for audio to two different devices. You need to delay the audio at some point in the connection stream, or take the audio output from the display to the receiver.

Doesnt your blue ray player has lipsync-correction?

200 ms delay usually does the trick.
