// This class is used to compensate for the "IE, Popup, Flash, Windows Media Player 'dynamic loading'" bug.
// These technologies in combination seem to cause the parent "launcher" page
// to lockup after the popup window is closed (usually after 2 or more launches).
// So, instead of just simply using a Media Player object, we
// create an IFRAME and load a new document into it. The new document is responsible
// for creating the actual video object. When a new video is desired, the
// IFRAME is re-loaded, re-creating the Media Player object.
//
//
// Assumes:
// video.html is available
// default mp parameters (currently no way to pass in default params)
// video.html creates a video object named "pVideo"
// video.html does not currently support custom properties, like position and size to be set
// Event callbacks are available: Buffering, playStateChange
//
