Equivalent to ubuntu-restricted-extras for Debian

I installed Debian 6 on my 9 year old PC and I got a problem like I had with Ubuntu. It's about Youtube. I wanted to see a video but I couldn't because there was not adobe flash player installed.
For Ubuntu, I typed "sudo apt-get install ubuntu-restricted-extras". But I wanted a equivalent to ubuntu-restritected-extras for Debian.
So I googled and found out how to fix problems in Debian. In terminal, type the next commands:

1. su -
2. type root's password
3. echo deb ftp:// ftp.debian-multimedia.org/ squeeze main >> /etc/apt/sources.list
4. apt-get update
5. apt-get install debian-multimedia-keyring
6. type 'y'

And voilá! Now, you can see any video from Youtube or somewhere else.
