Forgot the other make.dvd.sh from cd.iso script I used that sets the 
proper checksums in the new install dvd.iso... strange it looks like it 
originally came from your build script sources?

ftp://147.156.163.89//linux/scientific/303/i386/misc/scripts/sl.scripts.060904.tar.gz
./sites/example/build/scripts/buildisoimages/make.dvdiso.sh

Perhaps this script or a combination would be better for producing a 
SL-4.4 DVD Install ISO? - Art
