My explanation was a little simple - but that's about as much as I know.  CVSNT 
uses an alternative algorithm when -kB is used.  The efficiency of the text 
based algorithm on binary files is relatively poor (especially when compared 
with its efficiency at storing text files).

More info is here:

CVSNT also can store Unicode files as text and the text diff algorithm 
correctly handles UTF-16 etc (which is common in Windows).   

I suspect the original poster may be storing Unicode files as binary (which is 
required to not corrupt them in traditional CVS), and they would be more 
efficient as -ku files in CVSNT (and then the users could diff/merge as well).

Or they may just be frequently modified binary files...
