-<h2><center>wx.MediaCtrl</center></h2>
-
-wx.MediaCtrl is a class that allows a way to convieniently display
-various types of media, such as videos, audio files, natively through
-native codecs. Several different formats of audio and video files are
-supported, but some formats may not be playable on all platforms or
-may require specific codecs to be installed.
-
-<p>
-wx.MediaCtrl uses native backends to render media, for example on Windows
-there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
-QuickTime backend.
-<p>
-wx.MediaCtrl is not currently available on unix systems.
