I think where you went wrong is on the cdrecored command line.  I've
found that if I don't use the "-data" option to cdrecord I end up with
a single large file named iso-image_filename.iso on the CD.  If I
include the "-data" option, I get a file tree on the CD.  More simply,
I use the following command to burn a cd:

  cdrecord -v -data speed=8 dev=<dev-id> <iso-image_filename>

The cdrecord man page says that -data is the default, but that doesn't
seem to be the case with cdrecord-1.10-14 on RedHat 8.0.
