I created a MovieMaker version on my Drake Equation presentation. This was fairly straight-forward using Dr. Pierce's Sample Video. My biggest problem was adding narration at the right moments.
I published the Drake Equation video on YouTube. You can view it here.
I embedded the video directly onto this blog entry, using the instructional video in YouTube Help. Simply go to the Embed window while the video is running, highlight code, copy and paste onto the blog editor (remember to be in the Edit Html mode when you paste).
