When you saved it in Windows Media Player do you have any idea what format
you used? (What ever you do, keep QuickTime out of this, it will only
complicate the problem. <g>)
My guesstimate is that you used a codec that is not available to the Windows
MCI Player (Used internally by PowerPoint). You can examine the codec used
with a utility like GSpot, locate the correct codec on the internet, and
then download and install it. The issue then wil be if you plan to move the
presentation to other machines. If so they may or may not have the codec
installed so it may or may not work.
There are a couple of alternatives. You can recompress the video into a
more standard format with a more common codec. Something like Windows Media
Encoder or Stocick video encoder will do this if you are familiar with
encoding video.
Another alternative is to download the free trial version of PFCMedia
(
www.pfcmedia.com) and allow it to do the task automatically. Once inserted
with PFCMedia it will "PlayForCertain" on other Windows machines and
PowerPoint or PowerPoint viewers.
