How to correct original DVD's audio delay copying to DVD-R?

[emr]

Sorry if this is a FAQ but I searched and did not find anything suitable.

I have the European R2 Ghost in the Shell DVD. The film is fantastic but the DVD's not so great. There's a constant audio delay of about half a second or a little bit more. Even though this is animation, the synch problem is pretty irritating.

Is there an easy way to correct this while copying to a DVD-R? The whole disc is less than 4 GB so I shouldn't have to do any video recoding or anything like that but just reduce that delay. Any ideas?

use dvd2avi to split out the audio
use ISOBuster to split out the video (which will include the old audio)
use TMPGENC to either insert or cut 1.2 second of audio
use TMPGENC to mux the video and new audio back together
use TMPGENC DVD Author to reauthor the video

There are other ways, but this would be the basics

Thanks, that was a fast answer. Unfortunately that does not sound like a very easy way. And I forgot to add that I'd like to do it with free software if possible. I have an old VirtualDub version that seems able to add a negative delay to the audio track of a MPEG2. However, it seems that it's only possible to save the result as an AVI.

Anything easier? If not, it might be a better idea to buy the R1 or the newer R2 version without the delay.

EDIT: typo corrected

All of the apps mentioned are either freeware or trialware.

What are you thinking would be easier??????

The steps are that you have to add/remove an amount of audio and then splice it together and then make it a DVD again.

Although the replies was an answer to your question, I am afraid it is not the solution to your problem!

Be aware that the sound delay is not on the DVD disc but is caused by your DVD player not able to handle the high bitrates used on the DISC.

So although the answers given above will work more or less for that specific DVD player, you will get out-of-sync problems when that new created disc is being played on another DVD player.

Better solution is to recreate teh whole disc with lower bitrate settings, which your DVD player can cope with. You will see that your delay will be gone. Even better: the disc will still be playable on other DVD players!

Hope this helps.

@ JGJ, I don't see how that's possible.

But for benefit of the doubt, poster should try on more than one player to see how error works on others.

UH? Is there really a max bitrate for the audio on a DVD.

Be aware that the sound delay is not on the DVD disc but is caused by your DVD player not able to handle the high bitrates used on the DISC.

JGJ, could you tell what gives this idea? Do you have some insider information?

I have two DVD players, a newer harman/kardon DVD25 and an older Pioneer DV-525 which is notorious for it's lip synch problems. On some discs I notice the lip synch problem but that's not really significant in general. The problem with my GITS is on a totally different level and I really suspect a mastering error. The delay is clear on both my players and also on other people's players. The video bitrate is actually rather low, often somewhere in the region of 3 to 5 megs. With the Pioneer I'm currently sitting next to I can't see the audio bitrate but I have a feeling it's nowhere near the limits of the standard.

put it in your software dvd player on your computer and play it and see if you have a synch issue (you probably wont). The poster that mentioned the actual player may be correct.

Another possibility (using this as an example) were CVD's that I made. When played on my apex 1100w, sync is perfect. On my apex 1225, those same CVD's have a 1/2 second synch issue. It may not be a bitrate issue, but some other issue that is causing the actual problem. It is true that your newly authored DVD will have "A" synch issue when you put it in the next dvd player.

Guys, I do not follow your reasoning about the problem being with the player and not the disc. I have have something like 200 to 300 DVD's and this is the only one with such a huge delay. This particular DVD release has been also replaced and I suspect due to the well known synch problem.

macleod, I do not happen to have any (!) working software DVD player in my PC. I only have the videoLAN player which for some reason always crashes my w2k system - with every disc.

It's the disc, not the player.

The UK release of Ghost in the Shell had a very bad batch (or was it all of them ). They all contained the sync problem (so does my copy).

I got this:

"But there is a major flaw with the DVD version the sound isn't in sync with visuals for example the sound is always about 3 seconds behind so when the characters mouth stops the words keep coming. At first I thought it was just my copy but its true for every copy."
