Hey everyone!I have a small problem and I am sorry if this isn't in the right section but I couldn't figure out anywhere else to put it. A few years back I transferred some of my video tapes to dvd. The vcr I used back then only had 1 audio jack therefore when I go to watch the dvd on my computer there's only audio coming out of one speaker. Also when I go to watch the dvd on my television the audio is really low due to there only being audio coming from one channel. I now have a connector that takes care of that problem when I transfer tapes using that vcr. However, some of those tapes are so old I really can't transfer them again with as good of an outcome in quality as I did back then. So, I was wondering, is there a program out there that will let me re-author the dvds and add the audio to the other channel or speaker? I've been looking everywhere and I can't find nothing. Any help would be appreciated. Thanks

Copy the VIDEO_TS folder to the Desktop.
Run AVStoDVD.
Set your preferences for NTSC/PAL depending if you are in North America/anywhere else.
Open VTS_01_0.IFO
Highlight and right click the Title to edit it.
Select the 'Audio' tab;set as stereo, 128 and 'Normalize' the audio.
Click 'Start' to save the new movie.

Thanks for replying. I am getting a box that says "2 audio files with similar filename found ". Should I check both boxes or uncheck both or just check one? Thanks again for the help

This was transcribed from a tape to a DVD and it had two audio tracks?
You can check both and when you go to edit the audio it should have buttons to click for each track.

Yeah, I transferred it from one of my video tapes. I'm not sure why it's saying it has to similar audio tracks. I'll see what happens. Thanks again for the help

Ok, I'm not doing something right. I just went through the process and it still only has audio coming from one speaker

Drag one of the VOB files onto MediaInfo and look at the audio - compare it to the original.
This image shows a video with a single channel and one with stereo.

Ok. I checked one of the vob files from the original and it says 1 audio stream: AC-3 and then it says first audio stream, 2 channels, AC-3

So the audio stream that only comes out of one speaker has two channels (stereo)?
It would seem that one of the channels is silent?
If you wish to pursue it, download Audacity.
Run it and click 'Edit' > 'Preferences' > 'Libraries'.
Assuming that you don't have them (try 'locate' first), download the mp3 and ffmpeg plugins.
http://www.videohelp.com/tools/Audacity
After that, drag the VOB file into the window.
Look to see if there are two channels and see if both have a waveform.
If one is a flat line, you know that there is a problem.
Should look similar to this if both are good.

Well for some reason the bottom one has a straight line across it

That would be why you can't get anything out of that channel.
To fix it you can demux the video and audio to separate streams, correct the audio in Audacity and export it as a new file, then you mux the video and new audio back together into a new DVD and burn it to disk.
It's relatively simple to do if you want to try it.

That sounds great. I know how to do it all besides muxing it back together. Would you happen to have any suggestions on that part? Thanks again for all the help

MuxMan can take demuxed .m2v and .ac3 and create a new DVD folder.

One last question. What program would you recommend to de-mux the video and audio with? I usually just use TMPGEnc, then I've just figured out that I split the stereo to mono which will give me sound out of both speakers, using audacity. I save that file and the mux the files back together using Mux Man. Anyhow, if you might know of a better program to de-mux the video and audio I would appreciate any suggestions. Thanks again for all the help

PGCDemux - included with AvsToDVD
If you have chapters, you can save them from PgcDemux (Celltimes.txt)and load them in Muxman with 'File' > Import Chapter
You may want to 'Check a/v delay' in PgcDEmux - if it exists you can insert the delay factor in MuxMan.
