I offer a small improvement:

If you're going to write a shell script you might as well include the
user commands before hand as part of the script.  At least that's what
I first thought; however in this simple case you're better writing it
on as a one liner:

wget -qO - https://www.defcon.org/podcast/defcon-16-video.rss | grep
m4v | cut -d '"' -f2 | wget -i -

Redirecting everything through stdout/stdin has the advantage of not
leaving temporary files on your disk.
