I just finished wathcing a movie onan LCD projector I noticed that the audio was out of tune on only some scenes. What's up with that? I never noticed this on my DLP.
Is there a way to sync the audio with the video?
For the LCD projector it does video only so I send the audio directly to the speakers and the video thru a S-video cable to the projector. The video seems smooth I was wondering if the LCD needed more procesing time on diferent scenes.

Some DVD players have the ability to adjust the audio for this purpose. You should read up on your projector to see if others have had this problem. It's possible that the projector takes a long time to upconvert the signal to its native resolution. Is S-video the best connection you have available?

It does not seem to be an issue with the projector. Unfortunately it is a high def (1080p) projector and a 480i/p dvd player ( I currently do not have component cables) so I have to let the projector do the scaling and deinterlacing.

I guess I could try three composite cables and use the video (yellow) cable of each to make a component cable [will this work ? ] and see what happens.

Do I need to buy a new receiver with scaling and deinterlaceing to sync up the audio and video? Is there a cheaper solution ?
New receiver will handle all input. New upscaling DVD will only do DVD. Any good Blue-ray player in the $200 - $250 range??? what video processors do they have?

The weird thing is that the sound will be fine then slip for a few minutes, then recover, then slip. This is very annoying.

Hi Motororo2,

I seriously doubt it's the projector. The scaling / deinterlacing on a projectors scaler is likely to happen within 2 frames, and would be constant ... it wouldn't slip in and out. Most people can't detect 2 frames of audio lag.

I think it's more likely your player. Your least expensive solution would be a better DVD player like the Oppos ( that also include audio delay ), or one of the soon-to-be-firesale Toshiba HD-DVD players.
