Hi,
I have a DVD that I need to fix, but all the bits and pieces of information I have gathered from various forum is confusing me. I am not quite sure which programs to download / use in order for me to fix this one technical difficulty.

I have a dvd that is dubbed and the 2 audio languages are vietnamese and chinese and they are on 2 different audio tracks. The default language is vietnamese and there is one section of audio (towards the end of the dvd) that is not the correct audio for that section of video. I have a disc with the correct audio but the video for that disc is pretty bad. What I would like to do is take the correct audio from the one with bad picture and put it into the one with wrong audio and good picture without losing the chinese dialogue from that section either. I would like to keep the picture quality and all chapter and title menus and everything else on the disc the same.

Which program / software would I need to achieve this? I have downloaded, so far, the following software:

Mpeg2Decoder
MPEG_Streamclip_1.1
VideoReDo-1-6-1-268
cryvideodub
Yamb-2.0-Preview
vobedit06
VirtualDubMod_1_5_10_1_All_inclusive

I also have DVDDecryptor and DVD Shrink and Nero Burning Software.

The dvd has vob files and ac3 audio format. The good dialogue that I want to replace is in .wav format.

I have tried to demux the audio and video using DVDDecryptor, but the video is split up. Is there a way I can keep it one file? And how would I remux it with all the other stuff on the dvd with the video that has the new audio?

Any help would be much appreciated. A step by step of what to do is even better (I'm a little new at re-creating dvds and knowing the ins and outs of them. All the info I have are from the other forums that I have read).

And also, how would I sync them?
