Do we really need them to burn a DVD? DVD burners/readers are getting harder to find. It seems like you want this to bootstrap the Tails Installer, which is easier than using `dd` on the command line to install it. I might add a line here that says "If you can't or don't want to burn a DVD, see the [Tails documentation](https://tails.boum.org/doc/first_steps/installation/manual/index.en.html) for alternative instructions.
