Lots of teachers and students use Microsoft PowerPoint in education. I use it for many things and it is very powerful.
However, embedding videos and having them actually play correctly is not straightforward and if you move the video file or PowerPoint file without the other, things get ugly.
Freewaregenius has a nice article that tells you now to covert the video file into a flash file and then embed it directly into a single PowerPoint file. If you use PowerPoint and videos, this is a great resource for you.
