Using PP2007 I made a presentation that includes a short video clip (wmv). It plays properly on the machine where I created it, the clip is in the same folder as the presentation file, from where I linked the two. It's set to autoplay.

When I try to play the presentation on a different machine that lacks PP2007 but includes the viewer 2007, both files in the same folder, the presentation works but the video clip does not play. Its starting frame appears on the slide but the video doesn't play and there are no starting controls.

Also tried embedding Media Player using the developer tools. No go here too; clicking on the video controls in the viewer slide just advances to the next slide.

How can I get a machine that lacks Office to play the PP presentation properly?
