smallest encoding/compressing

[T.F. Cheng]

hi guys, 
  I am encoding/converting some VOB files into mpeg4
by mencoder, I run "mencoder xxx.VOB -ovc lavc
-lavcopts vcodec=mpeg4 -oac lavc -lavcopts
acodec=mp3:abitrate=48 -o yyy.avi", the file size is
usually 1/5 of the original, I wonder if there is any
other way/option to do this, and make it even smaller?


thanks



Best Regards,

Tsu-Fan Cheng
