Warp answered that: Why should mencoder choose for you which library
you should use?
I think the problem you're dealing with is that mencoder is meant to be
somewhat general purpose. I can easily imagine another encoder out there
that's as easy to use as you want, but would simply be inflexible - lack
of choices. mencoder is designed for flexibility.

They give various examples at the end of the man file. Yes, MPEG-1 is
not explicitly provided, but then why should they provide that over,
say, MPEG-4 or some other codec? I think you're mistaken in thinking
that most people do encoding into MPEG-1 - it's usually to encode to
xvid, divx or something similar.
In any case:
mencoder "mf://*.jpg" -mf fps=25 -o output.avi -ovc lavc -lavcopts
vcodec=mpeg4
It shouldn't be too hard to go from there to mpeg1.

Right in the beginning of the section for lavcopts, you see:
EXAMPLE:
vcodec=msmpeg4:vbitrate=1800:vhq:keyint=250
Should be enough of a hint.

Can't say I figured everything out by reading mencoder man file. I have
in the past done Google searches and looked at other people's scripts.
However, it's not obvious to me how it can be made better.

xvid is not exactly rare.
I'd be curious to see if the same command you're giving will produce a
working avi file on my side...
