Try the new (?) k9copy
for KDE. It works beautifully. Debian packages here
or APT sources here
It can do the shrink thing and its FLOSS and its very easy to use. It will save your Audio TS and Video TX folders into a designated folder (default is /tmp/dvd) which can be saved to keep these folders for every movie, but even easier is that it can make an *.iso of the movie for easy disk making, or burn the output directly (if you have two dvd drives and one is a writer).
After too much struggling with DVDShrink and Wine, this is perfecto. I love it!
