Alas, that didn't do the trick.  The ISO image created by the above dd 
command is identical to the one without the bs=32768.  I also tried 
using bs=16384 and bs=65536, but they both produce the same results as 
dd=32768 or omitting bs entirely.

One thing to note that the size difference for all three ISO images 
(between the originals and those created from the CDs with the dd 
command) is 307200, which is 300*1024 (or 75*4096).  Can anyone find 
any relevance in this information?

At this point, I have resolved my original problem.  I'm now just 
trying to satisfy my curiosity.

Thanks,
Alfred
