Tips:
Always put the movie in the same folder as your PowerPoint presentation. If you later move the PowerPoint presentation to another computer, copy the movie too. Keeping your movie in the same folder as your presentation ensures the link will still work. However, you should always test the movie on a new machine just to be certain. Re-insert the movie, if necessary.

Notice: The movie files that can be embeded into PowerPoint must be asf, avi, mpeg, or wmv. So make sure you have taken the right video format during the first step.

2. Click the video you want to use and then click OK.
4. Right-click the movie object (the small rectangle) and on the shortcut menu, click Edit Movie Object.
Test this now to see how it works by starting the slide show. (On the Slide Show menu, click View Show.) Advance to the slide with the movie, (best if you have the title of the movie on it). Within a couple of seconds, the movie starts to play full screen. When the movie finishes, you return to the same slide (but no unsightly box appears). Click to advance to your next slide.
