A couple of guesses:

- If dirname is an absolute path then you are including the drive 
specifier in the path in the zip file. If dirname is a relative path 
with elements like '.' or '..' then you are including them in the zip. 
Try something like
   fullname = os.path.join(root, f)[len(dirname):]
to get relative paths in the zip

- WinZip puts empty entries for directories in the zip. Maybe WinXP 
requires these.
