Were you intending to download what you need somewhere else,
put it on a disc, and transfer it over?
Here's your basic problem. You need several files to get this
working. That's what all the gobbledygook was all about.
There are pre-compiled binaries for all of them, and getting
them with the package manager (Synaptic or apt-get) is fairly
trivial. If you're not using that, you're going to have to
make sure you know what they all are and go find them
individually, download them, then install them. It can be
done, but it's not going to be "simple" as you mean
it.
If the machine is hooked up to a network, you can open a
terminal program and enter the following command:
sudo wget http://www.medibuntu.org/sources.list.d/hardy.list
-O /etc/apt/sources.list.d/medibuntu.list && sudo
apt-get update && sudo apt-get install
medibuntu-keyring && sudo apt-get update &&
sudo apt-get install libdvdcss2 w32codecs gstreamer0.10-ffmpeg
gstreamer0.10-plugins-ugly
gstreamer0.10-plugins-ugly-multiverse
gstreamer0.10-plugins-bad gstreamer0.10-plugins-bad-multiverse
You can just cut and paste that into the command line area and
hit enter. That will take care of everything.
Otherwise, you'll have find download sites for all those
packages.
Yes, this is the point where you may start to question your
choice of Linux. :)
It's really easy if you're network connected, not so much if
you aren't.
