How can i disable full screen button on JW Player 6?

I tried the following code:

<script type='text/javascript'>
    jwplayer('video').setup({
        height: 267,
        width: 475,
        autostart: true,
        enableFullscreen: 'false',
        playlist: [{
            sources: [
                { file: "1.mp4" },
                { file: "1.flv" },
                { file: "2.webm" }
            ]
        }]
    });
</script>

But not working enableFullscreen: 'false'. What is the way to do that? Sorry for my english.

UPDATE

I create my custom skin, but i can't hide the fullscreen button on JW Player.

<skin version="2.0" name="user92" author="user92" target="6.0">
    <components>
        <component name="controlbar">
            <elements>
                <element name="fullscreenButton" value="false" />
            </elements>
        </component>        
    </components>
</skin>

I have error on loading skin. What is the param that i have to set for hide only fullscreenbutton?. No all controlbar.

LAST UPDATE

OK. For hide the fullscreen button with the skin. You should assemble all controlbar, Omitting buttonfullscreen options

Solution

In JW Player 6, removing the fullscreen button can be done via our skinning model:

http://www.longtailvideo.com/support/jw-player/28847/building-jw-player-skins http://www.longtailvideo.com/support/jw-player/28849/skin-xml-reference

The SDK is available here - http://developer.longtailvideo.com/trac/

Basically, in the skin XML file, there is a section for the fullscreen/normalscreen button on the controlbar, which you can remove / comment out.

This section can be removed / commented out:

<element name="fullscreenButton" src="fullscreenButton.png" />
                <element name="fullscreenButtonOver" src="fullscreenButtonOver.png" />
                <element name="normalscreenButton" src="normalscreenButton.png" />
                <element name="normalscreenButtonOver" src="normalscreenButtonOver.png" />

Hope that helps!
