encoding avi with ffmpeg playable on Windows with Realplayer,Quicktime

[TrupsT]

I am creating a movie from frames using the following command.

mencoder "mf://*.jpg" -mf fps=25 -ovc lavc -lavcopts -o test.avi

And then I add an audio stream to it.

mencoder -oac copy -ovc copy -o Final.avi -audiofile audio.wav test.avi

This movie was not playable in windows,

so I made the following change.
mencoder "mf://*.jpg" -mf fps=25 -o test.avi -ovc lavc -lavcopts vcodec=msmpeg4v2

Now I am able to play it with Windows media player/Winamp etc, but not with Realplayer and Quicktime which is the need.

Please tell me what should I do.
Thanks in advance

you could try with libx264, should be compatible with all players you mentioned
