You'll probably be disappointed with the results, as it will 
dramatically impact your frame rate, but -

Comments:
If a player’s alwaysBuffer is false, the movie it contains is drawn in 
front of all objects. The visual effect command does not affect the 
screen area inside the rectangle of a player whose alwaysBuffer is false.

   Important!  If a player’s alwaysBuffer property is set to true, it 
cannot be controlled with the controller bar and must be operated by 
script control.

   Note:  Setting the alwaysBuffer to true always increases memory usage, 
and may make movie playing more jerky.

"May" is a gentle term for "will" in this case, as in "and WILL make 
movie playing more jerky."

This is not the fault of Revolution - it is always the case with laying 
content on top of a QuickTime. If you can live with it, then there is 
your answer. Most have to develop an alternate layout where overlay is 
not required.
