Hi Nader!
I am not sure exactly what you are talking about here.  I did notice that the file size of the ISO (the disk file image) was slightly larger than the resultant CD as indicated by the burning program.  I am glad that my burning program checks the MD5 sums (a file integrity check) before it burns the image.  It is always good to do so (see link):
You should find a list of the file MD5 sums on the same site you downloaded the ISOs.
I am suspicious that the differences in ISO image file size and resultant CD size is caused by the boot and metadata portions not being counted as "data" (see link):
However, there is probably some overhead just in the ISO9660 file system (see link):
And the truth is I really do not yet know for sure (and need to go to sleep now).
