 102
 103 wx.MediaCtrl is a class that allows a way to convieniently display types of
 104 media, such as videos, audio files, natively through native codecs.
 105
 106 <p>
 107 wx.MediaCtrl uses native backends to render media, for example on Windows
 108 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
 109 QuickTime backend.
 110 <p>
 111 wx.MediaCtrl is not currently available on unix systems.
