How to increase sound level



I am using the trial version of DVDFab Platinum
I am trying to copy a DVD using “Main movie” option.
In the “Common settings” section I can not see any option to control the volume level.
How can I change the volume level in the output DVD of some original DVDs that come with a very low sound level.


The short answer is that you can’t. DVDFab doesn’t decode the audio, just copies it. If you use Platinum’s DVD to Mobile modes to make AVI/MP4 files, there is a volume control there.
