The MCI player (used by PowerPoint and not to be confused witht he Windows
Media Player) won't work with an MP4 video natively. You might be able to
get it to work on a specific machine by changing the system settings and
codecs, but it not work on any other machine.
The simple solution is to convert the file to a more standard format. You
may use a video editing pacakage like ULead or MGI. You may also use one of
the manual encoders available. To do all of this automatically and make a
presentation that will Play For Certain on other machines I invite you to
download the free trail version of PFCMedia. (
