Hallo Jeff!

 JS> Any easy way to burn a directory and any sub-directories to a DVD.

Yes.  Use growisofs from dvd+rw-tools which will automagically create an iso 
from a directory and burn it to a DVD.

For example for multiple directories this should work;

  growisofs -J -R -Z /dev/dvd -speed=2 \
            -graft-points /directory1=/home/user/directory1 \
                          /directory2=/home/user/directory2

I don't believe there is any way to simply copy {,sub}directories to DVDs.  For 
that you'll probably want to use USB flashdisks instead such as this;

  cp -a /home/user/directory1 /home/user/directory2 /mnt/usbflash

where /mnt/flashdisk is wherever you mounted a formatted USB flashdisk.

Het leven is goed,
Maurice
