 138
 139 wx.MediaCtrl is a class that allows a way to convieniently display
 140 various types of media, such as videos, audio files, natively through
 141 native codecs.  Several different formats of audio and video files are
 142 supported, but some formats may not be playable on all platforms or
 143 may require specific codecs to be installed.
 144
 145 <p>
 146 wx.MediaCtrl uses native backends to render media, for example on Windows
 147 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
 148 QuickTime backend.
 149 <p>
 150 wx.MediaCtrl is not currently available on unix systems.
