This means that the AVI you want to encode is not a mjpege encoded AVI.
The mjpegtools can only handle mjpeg codec for the video and for audio
wav in AVI's every other codec will fail like this. If you can play the
movei back with mplayer, you can use mplayer and the mjpegtools to
create a MPEG file with a commands like that:

>mkfifo stream.yuv
>mplayer -nosound -noframedrop -vo yuv4mpeg anyfile.mpg &
> cat stream.yuv | yuvdenoise | yuvscaler -O SVCD | \
 mpeg2enc -f 4 -o video_svcd.m2v
>mplayer -vo null -ao pcm -aofile anyfile.wav anyfile.mpg
>cat anyfile.wav | mp2enc -o audio.mp2
>mplex -f 4 audio.mp2 video_svcd.m2v

Depending on your source you might have to change the commands for the
encoding. 

You find more information in the mjpeg-howto on SF, section: Creating
videos from other sources, and there subsection: Decoding streams with
mplayer
