   Yeah, ISO has been around a long time now.  It is still a perfectly
   valid format supported on most systems.

   But the VAX/VMS "ISO" is a misnomer.  It is not in ISO format, it is
   in Files-11 ODS-2 format.  That happens to be even older, and still
   completely supported by VMS.  The host that makes it doesn't need to
   know jack about it, it just needs to copy the blocks to the CD.

   Copying the misnamed ISO file to CD is a synch using the Disk Utility
   on a Mac.  There should be some tool for Windows, which, like Mac
   Disk Utility, does not care what is inside the file but just copies
   the blocks to the CD.

   Alternatively, dd on Linux or UNIX will accomplish the same thing.
