I'm a little blown away that Ubuntu 9.10 still has no DVD support and can't even install it. Pretty amazing 0_o.
Ah well, after seconds of googling I found a slightly popup laden answer:

Not bad. a) install Mediabuntu repos, b) install DVD support.
Still, it's 2010 and Ubuntu has no support for DVDs. In any way. Lame.

“To play DVDs, you also need to install libdvdcss by opening a terminal and entering the following in addition to installing the restricted extras package:
” sudo /usr/share/doc/libdvdread4/install-css.sh”
This is all officially documented, and the reason is because CSS “circumvention” is still illegal in major parts of the world. There is nothing Ubuntu can legally do about it and still offer their distribution for free.

So the conclusion is that the dmca and software patents suck more than ever, since the take the whole world down with them.
