What I've found that works fairly well is to do the following steps:

1.  copy the DVD installation tree from the DVD .iso to a working directory
2.  copy available updated RPMS (typically with "rsync") from a mirror 
site into the CentOS/RPMS directory
3.  use the "repomanage.py" utility from the "yum-utils" package to 
remove superseded RPMs (with the "-o" argument):

repomanage.py -o <base>/CentOS/RPMS | xargs rm -f

4.  Regenerate the hdlist file on the DVD image (requires the 
anaconda-runtime package to be installed):

/usr/lib/anaconda-runtime/genhdlist --productpath CentOS <base>
