  I'm a command-line junkie and don't use GUI tools for CD stuff.
"cdrecord" and "misofs" are all I use.  :)  Regardless, I never
actually burned the DVD image in question.  This was all about reading
and comparing.

  Hmmm, well, this is not an audio disc.  :)

  The disc I had was stamped, not laser-recorded.  I suppose Red Hat
might be making their release master using laser recording, and then
delivering that to the disc producer.

  And what did you find?  :-)
