Rewind Captivate movie in PowerPoint

If you deselect "Borders" under Project/Skin the navigation bars are included in the resulting swf. Which you can embed in powerpoint.

There is some little trickery with VBA you can use to start the movie automtically:
(sorry it is partly in german because of my program skin)

In Powerpoint open the Toolbar „Steuerelement Toolbox“ or open it with (View / Symbolleisten / …).
There click on “weitere Steuerelemente“ klicken (Symbol with a hammer).

In the alphabetical dropdown list select „Shockwave Flash“ .The mouse changes to a cross with which you can open a rectangle on the slide. There the video will appear later. Now it is filled with a big "X".
Right click on the rectangle and select "Properties". There behind "Movie" enter the name of the video (if it is at the same location) or the path.
If you choose TRUE after "embed movie" the resulting powerpoint presentation contains the flash movie, if you choose "false" it just links to it. So you can either assure that the video is part of the presentation or you can update the presentation by naming a new video identically to the old one and the link in your presentation now shows the new video (do you understand what I mean?)

If you start your presentation the video starts (even if it is on the last slide). You can restart it automatically by doing the following:

Double-click on the rectangle whre your video will be shown. The VBA editor opens in a new window. There click on Insert/modul in the toolbar.
The modul is a editor-window where you now place your code. Copy&Paste the following (example from me for three movies just edit it depending on your needs):

Sub OnSlideShowPageChange()

Dim film1 As ShockwaveFlash
Dim film2 As ShockwaveFlash
Dim film3 As ShockwaveFlash
Set film1 = ActivePresentation.Slides(2).Shapes("ShockwaveFlash1").OLEFormat.Object
Set film2 = ActivePresentation.Slides(3).Shapes("ShockwaveFlash2").OLEFormat.Object
Set film3 = ActivePresentation.Slides(4).Shapes("ShockwaveFlash3").OLEFormat.Object
film1.Playing = False
film2.Playing = False
film3.Playing = False
film1.Rewind
film2.Rewind
film3.Rewind
film1.Play
film2.Play
film3.Play

End Sub

This is doing the following:
Each time you enter a slide with a flash-video the video is rewind and played from the beginning. In this example there are three videos in the presentation. Do not change the order of the commands or it will not work!
The numbers in ( ) are the number of the slide on which the movie is appearing (here: the 2nd, the 3rd and the 4th). The name of the movie which you can find in the properties behind "name" or "title" is also entered. If you make a mistake here the code cannot affect your movies. Keep in mind that the numbering of the slides in the presentation is to be used, not the numbering shown in the vba editor, which you can see on the left (where you also see your module)
In this example the movie „Shockwaveflash1“ is on the second slide.
Then click on "Save" in the vba editor and close the window. Now test your presentation... It should work just fine!
