Both should work fine in FW 4 or 5 Pro. Both include some (albeit brief) notations of how to attach the Actions and what all the ‘dials’ and ‘knobs’ do inside the Actions themselves. Note, it is possible to set up a slideshow using just Show/Hide Layer actions and Sequence timers, etc… from the built-in actions included in the FW core application. I believe there is a brief tutorial for that on the softpress.com website.
