Open Synaptic (System -> Administration -> Synaptic Package Manager). In Settings -> Repositories, make sure you have a "multiverse" repository activated.
Search for vlc and install it. You should also install vlc-plugin-esd, mozilla-plugin-vlc (and libdvdcss2).
Command line way
You need to check that a "multiverse" mirror is listed in your /etc/apt/sources.list.
% sudo apt-get update
% sudo apt-get install vlc vlc-plugin-esd mozilla-plugin-vlc
Graphical way
Open Synaptic (System -> Administration -> Synaptic Package Manager). In Settings -> Repositories, make sure you have a "universe" repository activated.
Search for vlc and install it. You should also install vlc-plugin-esd, mozilla-plugin-vlc (and libdvdcss2).

Habits of Effective People
1 Be Proactive
Being proactive is the opposite of reactive. It means to take responsibility for your actions, it’s about making choices.
2 Begin with the End in Mind
Define your mission and goals in life
What matters most to you?
Write a personal mission statement including what you want to have, to do,
and to be...
3 Put First Things First
Prioritize, and do the most important things first
4 Think Win – Win
Have an everyone can win attitude
Thinking win-win is the foundation for getting along well with other people
5 Seek First to Understand,then to be understood
Listen to people sincerely
Listen first, talk second; see things from another person’s point of view before
sharing your own.
6 Synergize
Work together to achieve more
Synegry is achieved when two or more people work together to create a better
solution than either could alone. It’s not your way or my way but a better way.
7 Sharpen the Saw
Renew yourself regularly
Body physical
-Exercise, eat healthy, sleep well, relax
Brain mental
-Read, educate, write, learn new skills
Heart emotional
-Build relationships, give service, laugh
Soul spiritual
-Meditate, keep a journal,pray, take in quality media

Why is Linux not affected by computer viruses?
Linux (and other unix-like systems) were designed from the group up to be secure and allow secure multi-user access and networking. The reason why the Microsoft Windows family of operating systems have so many viruses is that it was originally designed as a single-user system and much of the security has been bolted on as an afterthought. This means that many more (and more severe) holes will exist.
There are actually viruses for linux, but they are generally far less effective.
virus is a program, it must have previledge to do nasty stuffs.
It is no doubt linux has virus, but when you running your linux as a normal user the virus cannot do anything bad.
If you run Linux as root (the equivaleng to Windows administrator), linux will be vulnerable to virus too.
By default installation, Windows XP creates a user which has administrator previledge, while Linux creates a user which has a normal (restricted) user previledge. This is the fundamental differences, since many Windows applications expect administrator previledge it is very hard to use Windows as a normal user. While most Linux applications are designed to run under normal user.

The Most Popular Operating System in the World
What is the world's most widely used operating system? It's not Windows, Unix or Linux, but ITRON, a Japanese real-time kernel for small-scale embedded systems. ITRON runs onmobile phones, digital cameras, CD players and countless other electronic devices.
ITRON emerged as an ambitious Japanese initiative known as The Real-time Operating system Nucleus (TRON). Launched in 1984, TRON was designed to replace disparate computer systems with a unified, open architecture for a "total computer environment."
Its ultimate goal was to create "highly functionally distributed systems" in which all system components are connected to a real-time network. Professor Ken Sakamura, spiritual father of TRON, conceived the project as a social infrastructure akin to the electrical power grid or water supply system.
Linux Alliance
This alliance between TRON and Linux could put more pressure on vendors of proprietary embedded software. Proprietary software is costly -- vendors usually charge royalties for each microprocessor running the software -- and licensing terms are often restrictive. Moreover, nearly all of the giants in the consumer electronics industry are rallying around open-source solutions.
