The playback of my tv programs that are being recorded does not match the audio.It seems to be a one second delay. The connections to my Pioneer receiver are correct(I think). Should I be using an optical cable instead of regular RCA cables? I checked to see if I had a delay setting on my receiver but I don`t. I have recently transferred all of my home movies to DVD and the playback is fine. Is this a common problem with entry level recorders? Anything you can suggest would be great. Thanks

Depending on the connections you use, there will most likely be a delay as they are 2 separate signals. If you use digital connections this should reduce the lag. HDMI and Display Port are digital video connections, Digital COAX and Optical/SPDIF are digital audio connections.
Most sound systems will have an option for audio delay which you can try to set to make the audio match what is being shown on screen but this would be tricky as you would have to judge it by ear yourself.
When viewing on Digital TV:- Sometimes Audio and Video signal can not be transmitted simultaneously due to additional process time for the video signal compared to that of the audio signal. Often video signal takes more time than the audio signal to convert from analogue signal to digital signal in the Digital TV. It may result in mismatch of the picture and sound. In the TH-G30/40's HD AV Sync menu, you can adjust the audio signal delay for simultaneous AV signal transmission
1. Delay time can be varied in 10msec steps.(0 to 300ms) 2. Delay time is different between TV Brands.
So you need to adjust the delay time for correct lip-sync. The adjustment is listed in the instruction book page12
It seems to me that you have only got one set of RCA Cablec between the TV and VCR ( from VCR Video out to TV Video In), as such the VCR only works in playback mode, you need a second set of RCA cables (from TV Video Out to VCR Video In) then select the appropriate input (Video) for the VCR. make sure to follow the colour coding on the RCA plug / socket arrangement
When connecting VCR to TV. Verify all connections. First if the connection is with coaxial cable make sure you signal from outside is screwed to the cable input on VCR. Then the VCR/TV output has the cable running to TV input. If hooking up with RCA cables , which is the yellow, red, and white cables. Hook one side up to VCR output. Yellow for Video, while red/white to audio output matching the colors. The same is done to the Television input. yellow for video, red/white for audio. Do a test recording. Use a blank tape, not one already recorded on. Record about 5 minutes Stop recording , rewind and playback. You should see the difference.
Are you absolutely sure that it is receiving an audio signal?
What input are you using? Try recording using alternate inputs.
Audio part of a VCR is normally way more reliable than the video.
The exception is on high-end stereo types where they record the extra
audio signals using the video head cylinder in which case it can easily
Lip-sync error is a widespread problem caused when video is delayed and audio arrives too soon. Widespread enough that three different manufacturers make dedicated products to address it, in fact (see review link below for those three).
It is present to some extent in essentially all broadcasts and DVD?s. If you have a recently acquired DLP, LCD or plasma display it may have added enough additional video delay to make it noticeable but lip-sync error comes from MANY sources starting at image capture and continuing through post production and broadcast or DVD encoding and it is cumulative. There is usually enough lip-sync error in broadcasts and DVD's to cause a negative impact on viewer perception (Research done at Stanford showed this.)
Many people don't consciously notice it until it gets very large because it's such an unnatural phenomenon ( audio can't come before the action causing the sound in the real world) we apparently subconsciously avoid looking at the faces and seeing the lips move "after" the sound from them is heard. A study at Stanford proved this causes negative viewer perception even for those who don't notice it so this is something we all need to notice as you already have.
For those reading this who haven't noticed it, take a close look at the LIPS - force yourself to overcome your natural avoidance mechanism that keeps you from looking at the lips - and you will see lip-sync error you never noticed before. I think you will be amazed that you could possibly not have noticed it before. You will be seeing what JC is seeing. I even see it now on CRT TV's
and am amazed I never noticed it so it's very obvious some avoidance mechanism is at work.
And back to JC?s solution: I'd recommend one of these digital audio delay units. That way you can correct for ALL cumulative lip-sync error no matter what its source might be. Any one of these units reviewed will correct it ALL.
With any one of these units you can adjust for perfect lip-sync at the start of each DVD or broadcast and not disturb the image you are watching during that fine adjustment. I have had a Felston DD340 since 2004 (three generations earlier than the DD740 covered in the review) but it still has the most important feature of all these units from these three different manufacturers which is their "plus and minus" buttons on their remotes that allow you to tweak the delay while watching your material without upsetting the video your are watching.
My av receiver has a built in delay of 80 ms which isn't even enough audio delay to offset the video delay my plasma display adds but even if it were it isn't practical to adjust it for the changes in lip-sync error from program to program and DVD to DVD since it overlays the screen with menus when making the delay adjustment. With my DD340 (and any of the units reviewed) all you have to do is press the plus or minus button until you get perfect sync.
Here is the review I mentioned:
There are probably a couple of different ways to hook things up. One is you hook the VCR "in between" the indoor antenna & the set. Hook antenna to VCR RF/Ant In, then VCR RF/Ant out to the Antenna input on TV. Your VCR will then be able to record one channel, while you watch another on TV. To play back the VCR, or do any VCR setup, TV channel must be set to either channel 3 or 4.
The other way is to use the Video & audio input/outputs on the VCR & TV. You will need the appropriate cable(s). Match the VCR video/audio outs with the set of inputs on TV. Video and audio out on the TV go back to the video/audio inputs on VCR. In order to view VCR playback, menu setup, you will need to select that input (line, aux, video 1 etc.) on the TV. This hookup probably won't allow the recording of a second channel while watching one.
As regards the hft channels, I assume you live in an area where such is being broadcast. The TV can probably be put into a programming mode where it will scan for all available channels, and put them into memory, or they can be programmed manually.
