What exactly IS this statement doing:

./pool/main/1/linux-source-2.6.20/nic--modules-2.6.20-15 generic-di_2

You haven't given much info here, such as what system & OS you are currently running, or what you used to burn the DVD, but:

So, let's see.. You have downloaded the .ISO image of an Ubuntu CD and want to burn it so you can boot/use/install Ubuntu, yes?

Generally, you would do like this:
1. Download the ISO image.
2. Download the .MD5 file that goes with it.
3. Verify that the ISO image of the Ubuntu CD is correct, using the following command from a linux console window, in the folder where you have saved the ISO image:

md5sum filename.ISO

4. Compare the output of that command to the string contained within the .MD5 file you downloaded. If they match, then the ISO image is OK to use. If not, you have downloaded a bad image, and need to download it again.
5 NOTE: If you're running Windows, it also has a command to verify the md5sum, but I can't remember what it is.

Now, you need to burn the Image to a disk. I recommend a CD, not a DVD, for two reasons: The ISO image is a CD image, not a DVD, so the checksum of the burned disk may not end up correct if burned to a DVD. And second, burning a CD image to a DVD is a waste of a lot of space on the DVD.

In Linux, I would use 'cdrecord' to burn the Image. Do not extract it or anything like that, it is meant to be burnt as is, to the CD.
From WIndows, I recommend Infra-Recorder to burn the Image to CD. It's a free program and can be found and downloaded by Google somewhere.
NERO can be used, and people do use it, but reviews of NERO burning Linux CD's are mixed.

Lastly, Burn the image at a low speed, like 4x. Do not use Full-speed, as the disk is more likely to be burned badly.
