growisofs only can create file under DVD root directory?
 

i use:
growisofs -M /dev/cdrom -J -R /home/key/

i do have files under /key, but i just want to write key directory to dvd root, but the command i use just write all files under /key to DVD root directory, how can i do this?

What about removing that last / ?

So:
growisofs -M /dev/cdrom -J -R /home/key

Cool
