Well actually to narrow my question is mp4 part of the MPEG-4 package?
As far as I know, avi and mp4 are just container formats. So it really doesn't matter what file extension you have as long as it is xvid.
you can look at the -of <FORMAT> in general encoding options in the mencoder man page.
Currently supports -of mpeg OR -of avi. Default is avi.
It is still a Beta Code so beware. Also look at MPEG4IP project if you are curious.
