how to install VLC?

[sergepca]

Hi,

I have one question about the installation of VLC on my Ibook-YLD2.3
I can read this on the web site :

###############################

    /Install VLC with apt-get/

/ Add the following lines to your */etc/apt/sources.list*:/

/| deb ftp://ftp.videolan.org/pub/videolan/debian $(ARCH)/
deb-src ftp://ftp.videolan.org/pub/videolan/debian sources/
|/

/ For a normal install, do :/

/|apt-get update||apt-get install gnome-vlc vlc-plugin-a52 
vlc-plugin-mad vlc-plugin-ogg libdvdcss2|
/

###############################
###############################

I edit my source.list but terminal send to me message error :

###############################
###############################

/[root@localhost @@@]apt-get update
Failed to exec method /usr/lib/apt/
E: Method has died unexpectedly!
E: Method /usr/lib/apt/ did not start correctly
[root@localhost @@@]/

where is my error?
apt-get cannot install debian packages?
and what think about Mplayer and other?
how install them?

thanks a lot (and sorry for my english ;-)
