I just encoded your video with your command line using version MEncoder 
Sherpya-SVN-r33574-4.2.5 (C) 2000-2011 MPlayer Team.  The output was 
almost the same until the last "Warning, extension...", but it worked 
fine and plays in other player.  This is what you should have:

VIDEO CODEC ID: 28
AUDIO CODEC ID: 15002, TAG: 0
