unattended lenny install

I remaster a debian lenny install iso with a preseed in order to have a full unattended lenny installation, but at testing fase (installation) there still showing me the package manager windows asking if I want to scan another CD. I look all the preseed examples files googling around but there isn't an option on this. I attach my preseed.cfg and the isolinux.cfg in case you find any error

Imagination is more important than knowledge
