Maybe the right solution would be an "aspect" video filter?
IMHO using -aspect to specify it seems natural to me, but for autoaspect
you'd have to look at the video dimensions at the filter chain's end of
course.  The current situation where it is specified in -lavcopts is
not quite right IMHO.

Also, I think the avi header overriding the MPEG4 aspect is the right
thing.  Let's say you got an avi where the encoder set the wrong aspect
in the MPEG4 header.  You don't want to reencode and can't easily change
the MPEG4 header with mencoder.  But you _can_ use -ovc copy -oac copy
to create a new avi with the corrected aspect in the avi header.
