    I did a video production that is 1 hour long. After many months, I completed it. The video itself
    was completely finished. Since I was using uncompressed video, it was about 60 GB. I used TMPEnc to
    encode to mpeg2. Then I used Adobe Encore to create the DVD. Since then, I re-built my computer and
    I thought I kept the original uncompressed files so I can archive them but they seem to be gone for

    Now that I play it in a DVD player, it sounds loud to me, like double the volume of a regular tv
    show. In my editing program, I lowered the entire volume of the video to -12db (the DVD level). For
    some reason, it still sounds too loud.

    So, I have the mpg2 files. I want to lower the volume of the audio and re-render it. Will this cause
    the video to re-render also? I am trying to avoid that because I want the highest quality possible.

    You can use under "tools" select the
    adjust audio option. Then you can lower or boost the audio.
    You can see/hear the effect of the change using the preview

    You didn't mention which version of tmpgenc you used. Earlier verisions
    contain tools which can demultiplex the mpg2 stream, separating the video
    from the audio without any quality loss. You can do this and then pull in
    the audio stream in any decent audio editor, tweak the sound to your hearts
    content, and then re-author the DVD in Encore.

    For what it's worth, I find the my DVDs frequently have a higher audio level
    than commercial DVDs. I don't worry about it, but YMMV. ;)
