Peter, this tutorial may be of help.

There are two things I would do. First, check to see if there is an updated
video driver for the lap top. Second, download and install the Vista Codec
Pack.

This may solve the issues for playing it on the lap top, however, if you
move the presentation to yet another machine you may run into the same
issues. I would advise converting the video to a more PowerPoint (MCI)
friendly format.
