 128
 129 wx.MediaCtrl is a class that allows a way to convieniently display
 130 various types of media, such as videos, audio files, natively through
 131 native codecs.  Several different formats of audio and video files are
 132 supported, but some formats may not be playable on all platforms or
 133 may require specific codecs to be installed.
 134
 135 <p>
 136 wx.MediaCtrl uses native backends to render media, for example on Windows
 137 there is a ActiveMovie/DirectShow backend, and on Macintosh there is a
 138 QuickTime backend.
 139 <p>
 140 wx.MediaCtrl is not currently available on unix systems.
