[X4U] embedded video in pdf, broken?

[Rad Craig]

I have a .pdf file that has a video in it.  It appears to be broken,  
there is a button to click on so that it will play, but the rest of  
the page is blank, except for a small symbol that looks like a java  
icon kinda.  Similar to the Sync icon in OSX (circular arrow).   
Clicking on the button does nothing.  So my question is maybe its a  
link to a video instead of an embedded video?  Is there a way to take  
the pdf file apart or some other way to get the filename or URL of  
this video?
