[MPlayer-users] coding into mpeg

[David]

I would like to code some jpeg into a mpeg (not a mpeg 4 but only a mpeg).
Which is the string ?

I use 
mencoder "mf://*.jpg" -mf fps=25  -audiofile suono.wav -ovc lavc -lavcopts 
vcodec=mpeg4 -oac copy -o movie.avi

but with this I obtain a DivX.

Anyone can help me ?

tnx ;)
