Hi Tony,

I've tried this with no success, I get the same exception.
...
JFrame frame = new JFrame("VLCExample");
frame.setPreferredSize(new Dimension(225, 285));
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Canvas canvas = new Canvas();
frame.setLayout(new FlowLayout());
frame.getContentPane().add(canvas); // Added
JVLC jvlc = new JVLC(args);
jvlc.setVideoOutput(canvas); // Error here
frame.pack();
frame.setVisible(true);
...
However, note that the error appears when I try to set the JVLC output to
the canvas and I am forced to use a Canvas object so, as it has already been
created and added to the content pane, why does it fail with a "must be a
displayable component error"?

I'm using the new MediaPlayer class. I have launched the VLC Example added
in the Java bindings branch of the VLC 0.9.0 test 3 version that uses this
class with no errors with a MPEG-1 and a H.264 videos. Hope this helps.
