Replacing/Adding Audio To Completed DVD?

[hech54]

I have a completed DVD authored to my HDD. It was authored as a simple concert DVD
in an old version of TDA with menu bitmap images, chapters and song titles. How can I keep
everything and just replace the audio with an enhanced version of the audio(from the same
exact source - the already authored DVD on my HDD)?
I pulled one song from the DVD and enhanced it....and it turned out surprisingly nice
and now I might as well do the rest of the show with the same enhancement settings.
Any suggestions or am I in for a world of hurt and disappointment?


I'm guessing replacing the audio would be MUCH easier than adding it as a second
audio.

Pgcdemux to extract all streams from your current dvd.
Muxman to author the old video with the new audio.
Vobblanker to add old the menu to the new authored dvd.

Thank You Baldrick!!!

Worked like a charm. I even did it twice because I forgot to add the audio delay values. It made no difference anyway...
