Yes, MPlayer displays the correct aspect when playing the MEncoded
mpeg1. The problem is that the aspect isn't honored by at least three
free software players: VLC, Xine and FFPlay (FFmpeg player). Could
three different players be broken?

Unfortunately, I don't have a hardware VCD/DVD player to test if the
problem is with MEncoder's VCD encoding or the decoding of the
non-MPlayer software players.
