It's hard to say, since you're not posting the actual commands that 
you're using.  I'm inclined to believe that you're using a different 
path in each "tar cf - <dir>" command, which would put different file 
names in each tar stream.  If I do what you're suggesting that you do, I 
don't get different sha1sums.
