Need help to increase audio volume in DVD

[Artefacto]

Hi everybody, I need some help... I have a dvd with audio too low. I would like to make a full copy of that disc without loosing image quality, but increasing the audio volume in the new copy. What is the best way to do this? Thank you for your help.

You can't do it by just copying or by using copying software, at least that I'm aware of. With Nero you can manipulate the percentage of compression for the audio versus video but not increase the actual sound volume.

You would have to reauthor the entire movie using something like Adobe Premiere or similiar.
