Audio compression

[Barabba]

Hi guys,
big issue for me: I've some cultural DVD to copy which has audio track in PCM (that takes about 1/3 DVD space!), I would to reauthor the DVDs and mix some titles using recompression, but with DVD shrink for ex. I could only compress video and have to leave the PCM audio track. What a waste!
How can compress it to DD2.0 192kbps? (or eventually mono!).

Thanks for answers.

As far as I know, there isn't a one-click solution for it, but those guides are fairly easy to get a hold on.
