+     * This method may need to be 'fuzzier' in order to become more accurate.

+	 * - `audio` (string): This is an image that should be used as a
+	 *    placeholder for audio files before they're loaded (QuickTime-only).
+	 *    Can be any relative or absolute URL. Defaults to blank.
+	 * - `bgcolor` (string): The background color for the media, if not
+	 *    already transparent. Defaults to `#ffffff`.
+	 * - `height` (integer): The height of the embedded media. Accepts any
+	 *    numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
+	 *    and it is recommended that you use this default.
+	 * - `loop` (boolean): Do you want the media to loop when its done?

+	 * - `mediaplayer` (string): The location of the included
+	 *    `mediaplayer.swf` file. This allows for the playback of Flash Video

+	 *    placeholder for video files before they're loaded (QuickTime-only).
+	 *    Can be any relative or absolute URL. Defaults to blank.
+	 * - `width` (integer): The width of the embedded media. Accepts any
+	 *    numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
+	 *    and it is recommended that you use this default.
+	 * - `widescreen` (boolean): Is the enclosure widescreen or standard?

+	 *    the content appropriately.  Defaults to `false`, implying 4:3 mode.
+	 *
+	 * Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
