I'm also not sure what "load the movie into RAM" means to you or for 
that matter to the standard Java libraries. For instance, see the class 
description for MappedByteBuffer: 
<http://docs.oracle.com/javase/7/docs/api/java/nio/MappedByteBuffer.html>, 
and its isLoaded() method 
<http://docs.oracle.com/javase/7/docs/api/java/nio/MappedByteBuffer.html#isLoaded()>.
