<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.
