I use the term "slide show" as two words, but I'm unsure of the correct usage too! :)
It sounds like you want to add a video to your website, not a slide show, which is usually a set of photos or images. Please take a look at our online tutorial on how to upload a video, here: Upload my own Video.
I hope this helps! If you need further assistance, please let us know and we will help you further.
