Running DVD with menu(VOB) on VLC(Linux)

I have some dvds and i have linux(Ubuntu).I tried to open dvd different files(VOB) and it opens in chunks then i find that i not able view DVD menu(in Ubuntu ) as it viewed in windows media player.

I tried to find out the reason and i find that the possible way of viewing menu is after installing libdvdcss2.

The possible steps are
1)mkdir /home/<home dir>/libdvdcss2
2)/home/<home dir>/libdvdcss2
3)wget -c http://download.videolan.org/pub/libdvdcss/1.2.13/libdvdcss-1.2.13.tar.bz2
4)tar xvf libdvdcss-1.2.13.tar.bz2
5)cd libdvdcss-1.2.13/
6)./configure
7)make
8)If you dont have checkinstall and build-essential then install them
9)sudo checkinstall --pakdir /home/sandeep/libdvdcss2 --backup=no --deldoc=yes --pkgname libdvdcss2 --pkgversion "1.2.13" --fstrans=no --deldesc=yes --delspec=yes --default && make distclean && sudo ldconfig
10)Restart the system.

Now try to right click on(or drag) the .IFO file inside dvd and open(drop) it in vlc.And you will find the menu there. :D
