I just bought a new Samsung HL-R5078W DLP TV.  I hooked it up to my Denon receiver and JVC DVD player (sorry, I don't have the model numbers handy).  When I play a DVD, the timing of the sound of the voices doesn't match the movement of the mouths on the TV screen.  All I did was change the TV, everything else is the same.  Any idea how to fix it?  Thanks.

Dear John,

Ever see the "Monty Python" skit where everyone knew that their voices and the video were out of synch? Pure hilarity.

Is this happening on *all* DVDs?

Okay, this should not be happening. Delays in sound and picture transmission should be in the nano- region. Tell me how your TV is connected to your receiver and DVD player, please.

Also, allexpert Cleggsan is better versed on this kind of issue than I. Make sure you ask him the same question.

Kindest regards,

Kevin

The DVD player is connected to the receiver with a/v cables, s-video cable and an optical audio cord.  The receiver is connected to the tv with a/v cables.  Also, Cleggsan's name is not linked.  How do I ask him?

Answer
Dear John,

Make sure that your DVD player is connected to the receiver with only one cable/pair per application. In other words, use only the S-video for video and digital optical for audio. You don't need any other cables. Ditto the receiver outputs to the TV.

I ran across a situation once where a buddy had multiple connections between his VCR and receiver and the receiver and TV. The result was all sorts of misfunctions. If you use multiple connections, say, composite video *and* S-video and analog audio *and* digital optical audio, the receiver will not know which signal to send to the TV when. This could (underscore "could") be the cause of the time delay between sound and picture.

Another possibility is that you're running the video through the receiver. I don't do this as a rule. I prefer to run the video straight from the DVD player to the TV: fewer switches for the signal to run through and less of chance that it will be corrupted. This of course doesn't help if you have multiple video sources and only one external video input on the TV. In that case the receiver acts as the traffic cop. In all cases make sure that your audio and video are through the same set of switches. Don't put your video through Video 1 and its audio through Video 2. I know, a minor point...but you'd be surprised. A smart receiver will find everything, but maybe not at the same time.

I can't provide a link to Cleggsan. You'll find him as one of the experts in the TV/Stereo Troubleshooting main menu.
