However, the basic VLC executable is able to read the test dvds on windows operating System.
i don't know what you've done already, but i'll post you the instructions to use dvd's:
Code:
sudo apt-get install libdvdread4
sudo /usr/share/doc/libdvdread4/install-css.sh

it is quite straightforward as there usually is no compiling etc involved. behaviour of the drivers is not always the same in linux though.
if you mainly use multimedia, etc. you could check out Linux Mint Helena which is based on Ubuntu Karmic but developed for those transitioning from windows. a lot of these things should work straight after a system install.
