[plt-scheme] embedding movies in slideshow presentations?

Thanks! I've figured out how (in Windows) to launch an external MysterX 
browser with an ActiveX Media Player (source given below for posterity). 
The ideal would be if I could embed this directly within the slide 
itself. Is it possible to embed a frame% or an mx-browser%?

Otherwise this will do fine.

Thanks again,
Dave
