I guess he wants an MPEG-1 encoded video in an MPEG container, which is 
playable by Windows without installing any codec (that's the only good 
thing about MPEG-1 I can think about...) and thus he should use this 
command to obtain it:

mencoder "mf://*.jpg" -mf fps=25  -audiofile suono.wav -ovc lavc 
-lavcopts vcodec=mpeg1video -oac copy -of mpeg -o movie.mpg

If you want the final video to have a certain resolution, lets say 
640x480 add: "-vf scale=640:480" so you finally have the string:

mencoder "mf://*.jpg" -mf fps=25  -audiofile suono.wav -ovc lavc 
-lavcopts vcodec=mpeg1video -vf scale=640:480 -oac copy -of mpeg -o 
movie.mpg

Hope this helps.. :)
