 * StreamPlayer

 * @param string	containerId		#id of the container we are load player into
 * @param integer	w
 * @param integer	h
 * @param array		streamUrls		Array of stream url objects
 * @param bool		hasFlash		Does the user have flash plugin?
 * @param string	browserName		eg. "IE", "Netscape"
 * @param mixed		wmpMajorVer		Windows media player major version
 * @param mixed		wmpMinorVer		Windows media player minor version
 * @param bool		hasNetscapePlugin Is Netscape 6.4 plugin installed
 * @param bool		debug			Basic debugging
