Enabling External Media Objects in PowerPoint Viewer 2010

I have a Powerpoint presentation with embedded video clips.

The Smart Art doesn't animate correctly in Powerpoint 2003 (which, unfortunately, is still being used by a large number of people who need to view these files).

Solution 1: I packaged for CD and included PowerPoint Viewer 2007
Outcome: The Smart Art still DOESN'T animate; Embedded videos WILL play

Solution 2: Instruct the end users to download and install PowerPoint Viewer 2010
Outcome: The Smart Art DOES animate; Embedded videos will NOT play.

I discovered that if I open the presentation file in PowerPoint 2010 I get a warning that external medial objects have been blocked. If I click the Enable Content button, then close Powerpoint and go back to Powerpoint Viewer 2010 (on the same computer) embedded video WILL play.

How does someone who does not have the full version of Powerpoint 2010 open the presentation file and enable content?

This is REALLY important to solve immediately.

Thanks a million!


To make things even more complicated...

I just opened the Help menu in Viewer.
-> The Media tab indicates shortcuts for start, stop, volume, etc.

Then, I opened the readme file.
-> "PowerPoint Viewer does not support running macros, programs, or opening linked or embedded objects".


That's a bit contradictory, isn't it? Media IS an embedded object, is it not?!
