Install medialinux distribution package on knoppixHDinst

Ok,
first I installed knoppix on my HD, and it work good.
I've download a Knoppix Distribution call MediaLinux...
It is possible to do a apt-cdrom with a Knoppix live cd to install specific package...
When I look to my MediaLinux cd i don't see .deb file but just a big file call Knoppix... how can I extract deb file of this big file.
Thanks
MediaLinux URL:ftp://ftp.logx.it/mirrors/medialinux/

this file is also a knoppix-cd, but this time an modified version with much multimedia software. you can't 'update' your current system with this software. but you can use apt-get (or synaptic) to download and install the software you want... thats easy, there's an apt-get tutorial on this site, but I can give you some quick help:
to update the by-apt-get-known list of software on the web:

Code:

---

apt-get update

---

(you can change the list of sites apt-get looks at for software at /etc/apt/sources.list, you can find sources on the official debian website and on www.apt-get.org)
then you can upgrade your software with

Code:

---

apt-get upgrade

---

or do an extended upgrade (wich will include changed dependency's) with

Code:

---

apt-get dist-upgrade

---

to install software:

Code:

---

apt-get install [name of program you want to install]

---

and it will be downloaded, its dependency's will be fixed, and it will be installed.
for an graphical apt-get frontend:

Code:

---

apt-get install synaptic

---

synaptic is very easy to use. give it a try...

good luck!
