Motion-jpeg converter

[sun_ryan]

I need convert all kinds of media files into motion-jpeg(avi container).

Could anybody show me a suitable software?

Did you try MEncoder?
MEncoder.exe -oac pcm -ovc lavc -lavcopts vcodec=mjpeg -o "c:\output.avi" "c:\input.foo"

Should work with almost any input type, basically with everything that plays in MPlayer...
