That is fine about showing 629 MB (600*1024*1024), difference of base 10 and base 2. I am using "ditto -rsrc -V src_file dst_file", does it do any compression and copy the data.

No, ditto doesn't compress data (although on Snow Leopard it can make use of HFS+ compression).

When I burn it on DVD, it maintains the size.

Yes, it would.

I have tried "srcfolder" option and I can create compressed image. But when I burn this image on DVD, it expands to equivalent of size of data (around 1 GB).

Yes, a compressed image just stores the data for the image in compressed form but if you burn the image to a DVD it will be expanded. Still I can't imagine that’s a problem for you—it makes little difference if you use, say, half a DVD rather than three quarters of a DVD. At this stage I would suggest taking your problem off this list since it seems to have little to do with Darwin development.
