Audio is too low on a DVD

[ABMJR]

Friends, I have searched back about 5 pages and I don't see my problem posted...I have a DVD which which was compiled somewhere else, I received the file in ISO format and burned it accordingly to DVD....The audio is extremely low, not unbearable, but overall, it is low to the point that I have to have the TV's volume at 100 to hear them talking in a subdued scene....most of my other DVD's and Commercialy made ones are at level 9 and anything higher is way too loud...As you see a 9 to a 100 is a great leap...My question, How or better yet, what program can I use to rip/strip off the audio, de-mux it, and then re-author the sound and then mux it back?....Any help would be greatly appreciated...ABM

What OS(es) do you have to work with? I can tell you how to do it in Linux...
