Images disappearing when printing stack

[Barry Levine]

I've built a stack that has four cards. On each card is a player object 
that might reference a jpeg or a QT movie stored on the hard drive. 
When I navigate to each card I can see either the current frame of the 
movie of the jpeg appearing in each player object. When I print from 
the Mac, everything prints including the current frame of the player 
object. However, when I print from Windows, the player objects appear 
empty. Their borders are there but the content is just blank white. Any 
idea what I'm not doing?

Thanks,
Barry
