Hi All,

The solution to the problem (following the good advice received on this 
list) turned out to be:

1. Doing a clean install of CentOS 5 on a server and updating to latest 

Linux sable.cg-a.co.za 2.6.18-92.1.10.el5 #1 SMP Tue Aug 5 07:42:41 EDT 
2008 x86_64 x86_64 x86_64 GNU/Linux

2.  Using k3b - when doing this, do not select the "New data DVD 
project" option as this will not allow you to add the +-8GB iso file. 
Instead double click on the iso file and then on start.

3. Interestingly when this is done as root an error message:

:-( unable to anonymously nmap 33554432: Resource temporarily unavailable
Fatal error at startup: Resource temporarily unavailable

is output and the process stops.

4. When running k3b as a normal  user the process completes and the DVD 
is usable.

5. I am certain that it will also work using growidofs on the command 
line with the same options that k3b generates (although I have not 
verified this).

6. None of the above worked on my fully updated CentOS 4 box (it may 
have something to do with its being DOM0 for my virtual servers).
