DirectX problems with PowerPoint?

[Ranman]

I used to have a PowerPoint presentation that worked. The inserted avi
videos could be seen on all three computers that I have available.
I was about to Pack and Go the presentation to CDs for distribution, but I
thought it best to upgrade my Office 2003 with the latest upgrades. This
included Directx9.0c.
The avi videos are not showing... only the sound.
Yes, I checked and added the video codecs, read and followed the Myers
article, Sonia's great web site, and the PPTools instructional web site. I
check the gpot software and downloaded and installed the recommended codecs.
Still no video.
I re-formated my laptop with WinXP pro and then the Office 2003 group and
checked the presentation.
It works! However I see residual lines on the video as it shows when I
turned off the video accelerator.
Then I did something dumb... I upgraded DirectX again.
No video.
The knowledge base for Directx and Powerpoint do not show a conflict, or at
least any discussion of it.
Has anyone else had this problem? Any workarounds? I would hate to have to
reformat all my computers just for this presentation!

Thanks
Ran

As suggested in the Windows Media Video newsgroup, I
converted my avi file to wmv using windows media encoder
and then inserted it into the PowerPoint presentation. It
works! Does anyone know why the avi doesn't work in
PowerPoint yet works fine in all the media players I
tried? Does the new DirectX cause the problem? Updating
this was the only change I made. Is Microsoft aware?

The player that PowerPoint uses is mplay32.exe. Did you test the AVI in it? If
you're still interested in making it work, you might try lowering hardware
acceleration.

Yes the avi did work with the mplay32, as well as the
other two recommended media players.
Yes, I did turn off the ati video accelerator and the
video could be seen, but it looked terrible. Just
lowering the video didn't work.
The presentation does work now with the wmv videos, but I
was wondering if there was a problem with Direct Show in
DirectX 9. Just trying to help.
BTW Thanks for all the work you put in here and on your
web site!!
