The line regarding videolan (may be the line number 32) of /etc/apt/sources.list is wrong.

Please delete it, open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo gedit /etc/apt/sources.list

give your user password when requested, you don't see nothing when you type it, then press enter.

Save and exit then retry.

To install videolan (vlc)
--------------------------------------------------------

You need to have extra repositories enabled..

To enable all the software repositories:

Using System->Administration->Software sources [Ubuntu software tab] please enable (Check the checkbox) all the showed repositories rows.

after getting all the required repositories enabled

Type the following command in a terminal (applications -> accessories -> terminal)

sudo aptitude install vlc

To get dvd playback

sudo aptitude install libdvdread3 libdvdnav4 libdvdcss2

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps

Then be sure your system is fully upgraded, to check:
open a Terminal from the menu Applications->Accessories->Terminal and type:

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get clean all
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean all
sudo apt-get autoremove

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps

Better to get dvd playback you need to add the medibuntu repository to your /etc/apt/sources.list file:
here howto add https://help.ubuntu.com/community/Medibuntu

sudo update
sudo aptitude install libdvdread3 libdvdnav4 libdvdcss2

give your user password when requested, you don't see nothing when you type it, then press enter.

Hope this helps
