Collapsing DVD and CD torrents into one

Using multi-session recording of the DVD is not necessary.  As long as
you require loop-back mount, then you've got shell, cat, and dd.  So the
CD images can be constructed from files within a single-session DVD
by using one shell script per output platter:

      cat <leading-sectors> <directory-info> <file-list> \
   |  dd bs=32k of=/dev/cdrw

where <directory-info> is a file containing the directory portion of
the appropriate mkisofs.
