InstaDMG and 10.6

Hello all, I am using InstaDMG to make some 10.6 images with 10.6.3 combo updates and iLife installed. I have been able to get InstaDMG to run just fine and it even says it is installing the packages, but for some reason all I end up with is a 10.6.0 image with nothing installed. I did see this article on 10.6: https://www.afp548.com/article.php?story=20090918111532782 But I have no idea how to do this. Will this fix the problem I am having? I would appreciate if someone could give me some direction or point me to somewhere that covers this. Thank you!
