+ As you can see, <systemitem class="library">libavformat</systemitem>
+ allows <application>MEncoder</application> to mux into a considerable
+ variety of containers.
+ Unfortunately, as <application>MEncoder</application> was not designed
+ from the beginning to support other container formats than AVI,
+ your should really be paranoid about the resulting file.
+ Please check to be sure that the audio/video synchronization is okay
+ and that the file can be played correctly by players other than
+ <application>MPlayer</application>.
