Think of an .iso file as a zipped up package of an entire CD. It takes all the contents of a CD and make a huge file out of it. The .iso tends to be bigger than the actual disk at times, I think because it is probably because it adds configuration information as well. But who knows!

Any clearer?
Yes a bit, you are probably right about what to do to get Nero to burn from an iso (never used it myself so I wouldn't know). Your description of the iso file is partly wrong though. It does not contain any more (or less) infromation than what will be written to the CD, it is exactly the same size as the finished disk will be, and the contents are also in the same format. IMO the best way to think of the iso file is a CD without the physical disk, once you attach it to a blank disk using the burner you get the finished CD. You can easily show that this is the case if you have a HD installed knoppix and more than 700MB free on the HD, for instance like this:
Code:
dd if=/dev/cdrom of=foobar
once that has finished you can compare the foobar file with the iso file you used to create the CD (with diff for instance) and you will see that they are identical, assuming that the burning process was done correctly earlier.
