I  had  similar  problems.  It  seems  xvid  has  a  compression limit at high
bitrates. The file size of the result then only changes unnoticeably by  about
1MB  even  if  you  increase  the  bitrate by 1000. I there for changed to use
ffmpeg with mpeg4. It is a free codec with mpeg4 chosen as the method,  as  is
xvid,  just  better  and  much  quicker.  It  comes  from  the  ffmpeg/mplayer
developers. You might have to delete an f in  the  source  of  ffmpeg  to  get
second pass to work. See other threads.
