  mencoder input.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=300 -mc 
0 -ofps 25 -o output.avi

What's the source fps?  I've seen stuff like this when I used the wrong 
fps.  You probably don't need to specify it.  Are you using a 2 pass?  
XviD is usually  like this, seperating the audio and video passes:

mencoder input.avi -oac mp3lame -ovc -copy -mc 0 -ofps 25 -o output.avi

mencoder input.avi -oac copy -ovc xvid -xvidencopts pass=1:turbo -mc 0 
-ofps 25 -o output.avi

mencoder input.avi -oac copy -ovc xvid -xvidencopts pass=2:bitrate=300 
-mc 0 -ofps 25 -o output.avi

This keeps from running the same mp3lame 2 times.  Speeds up overall 
times.  Also, why such a low bitrate?  If theres any kind of movement, 
a 512 or 768 may give better quality.

Good luck.
