Powerpoint Presentations with AVI files won't play correctly in VI

[buddyddog]

Both powerpoint 2003 and powerpoint 2007 AVI files
won't play in windows vista unless extension is changed from AVI to MPG.
These same AVI files play in VISTA Windows Media Player. Powerpoint 2003 and
2007 AVI files play correctly in Windows XP. It looks to me as though the
problem lies with Powerpoint interaction with VISTA. I have emailed
Microsoft and it appears that they are unable or unwilling to resolve the
problem. Since I have too many presentations to correct by changing the file
extension, I decided to go back to Windows XP operating system where
Powerpoint 2007 works just fine. However, I will need to play these
presentations in VISTA as well. Is there any patch or fix available rather
than renaming the file extension to mpg and redoing all my presentations??
Thanks.

Are you sure you really wanted to post this in the Mac PPT group??

Do you know what codecs have been used to make your AVI files (AVI is a
container format and a lot of different codecs can be used to encode
audio and video).
