[Live-demo] Master for printing

[Brian Hamlin]

The MD5 checksum is sensitive to the byte, so it confirms you have an  
exact copy. I suspect that the MD5 on the .iso file is one check, and  
then an MD5 *on the physical media* is the second check. Past that.  
it is up to the DVD duplicators to do their job.

Please note that the USB sticks - 4GB or 8GB - have been popular in  
the past, but that even professional duplicators who swear that they  
can do it, have failed in the past to make them correctly. As noted  
on the master spreadsheet, our team has, including me, have burned a  
bootable USB with the OSGeo Live 7.

The DVD duplication should be straightforward.

   best regards from Berkeley, California
