Trying to explain a few things:
MPEG-4 is (amongst others) a collection of audio and video compression methods.
MPEG-4 ASP and MPEG4-AVC (aka H264) are two video compression methods that you
compare in your article.
Xvid, DivX and FFmpeg FMP4 are three implementations of MPEG-4 ASP, x264 is an
implementation of MPEG-4 AVC. DivX is the only non open-source implementation.
You did NOT test DivX (it's not possible with latest svn, there once was a patch
in the mailing list), with mencoder -ovc lavc -lavcopts vcodec=mpeg4 you tested
FFmpegs implementation of MPEG-4 ASP.
