Technology - I'm still learning

I've had some success lately and a failure, which makes it difficult to wile away hours on something and not have it work.
I was successful in putting a project together, with pictures and text, and copying it to a CD. I had to do this for UVM because I had to finish my graduate course. That seems pretty simple, but I tried three kinds of discs before one of them worked. I knew it wasn't the size of the project, only 4 pictures and 5 written pages of text, but getting the computer to transfer the work to a disc. My tech teacher told me to save the stuff in a folder, and that eventually worked.
My unsuccessful venture was today, actually. I had created, on a MAC in my library, a Keynote presentation that I made from photos and video I had taken of robins that had built a nest below my deck. The photos and videos took 2 weeks to gather as the birds matured and I was quite proud of how much you could see as mom and dad robin fed the babies. I wanted to be able to transfer the completed work to a CD so that I could show it anywhere. On the MAC, the movie was only 2" high and wouldn't work at all on my PC. I know that the easiest way is to have the original program on a laptop and run it from there, but I don't have a laptop or a MAC. When I leave this school, I really wanted to take it with me. I'll try again.
