Mpeg volume normalization

hi. i need a dvd authoring program where it automatically (or option) normalizes volume level. i’m trying to make a dvd out of 30 short video clips and volume leves are all different. i currently use tmpgenc dvd authoring software but it has no volume normalization. thank you.

I’m not aware of any authoring program that will normalize sound levels as that action has absolutely nothing to do with authoring.
