It's the alwaysbuffer property.

Buffered objects cause the card to load slightly more slowly but 
performance is better when they run. This mostly affects images. 
Buffered images require twice as much RAM because an offscreen buffer 
has to be set up that is the same size as the image. If your image isn't 
an animated gif, you may not notice much difference.

Buffered player objects allow the movie controler at the bottom to 
function; unbuffered players don't. Unbuffered players do allow you to 
create objects that sit on top of the player though, while buffered 
players always float on top of everything else.

I think (but am not sure) that other native controls like buttons and 
fields, are always buffered automatically.
