This has worked only by chance :-).
I think you mean:

 ffmpeg -i /home/ren/movie.vob  -f avi -vtag "DIVX" -vcodec mpeg4 
 -acodec mp3 -map 0.0 -map 0.1 /home/ren/movie.avi -acodec mp3 
 -map 0.3 /home/ren/movie.mp3

The -map ... stuff is slightly confusing, you simply specify the
streams in the order you want, per output file.  The additional
parameter after the colon is new, it specifies the input stream to
sync against.  Since you have only a single input stream, the "-map
0.3:1.0" fails.
