Unfortunately, when I launch K3b to try and burn an ISO to a DVD, it immediately lists 4 problems about things which are missing! These are cdrecord, cdrdao, growisofs, and dvd+rw-format. Why haven't these things been automatically installed? How should I install them? This has never happened to me with K3b on other Linux distros before.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

Those appear to optional dependencies, not implicit ones. Easy to resolve though:
pacman -S cdrdao cdrtools dvd+rw-tools
That should be enough looking at the Arch Wiki.
