Audio normalisation when backing up concert DVDs to MP3

At the risk of asking the obvious, I noticed that one of the steps that Auto Gordian Knot performs is to normalise the audio, and I was wondering why this is necessary.

Is it the case that audio encoded to commercial DVDs is somehow lower in volume than "normal"? Or is it just always good practice to perform audio normalisation?

What I have in mind here is several concert DVDs that I'd like to back up, both to AVI and to MP3. To get the MP3 audio, I was just going to retrieve the MP3 file from the agk_tmp folder that Auto Gordian Knot creates, and I'm just wondering if it might not be better to do it some other way in order to avoid the audio getting normalised. For comparison, when ripping CDs to MP3 with Exact Audio Copy and LAME, I don't perform any audio normalisation, so I'm wondering why/if I shouldn't also skip normalisation in the case of extracting audio from a DVD.

Sorry if I'm not understanding the process properly.
