You're right. It is a pre-mastered file system that just needs to be
recorded onto a media. The size 657922048 indicates that it would fit
onto a regular CD-R.

Yes, both will work, and yes, cdrdao is better for audio or mixed
forms (allthough it can burn data ISO, too, but I don't know how,
out of the box). :-)

You may follow my examples from Date: Sun, 25 Jan 2009 02:53:46 +0100.

I'm a lazy guy, so I've setup the following aliases in /etc/csh.cshrc:

	alias	burndata	'cdrecord dev=1,0,0 speed=16 -v -eject -tao -data'
	alias	burnaudio	'cdrecord dev=1,0,0 speed=16 -v -eject -dao -audio'
	alias	burntoc		'cdrdao write --driver generic-mmc-raw --device 1,0,0 --speed 16 --eject'

And I've got a shell script "burndvd" in ~/bin (included in $PATH):

	#!/bin/sh

	if [ "$1" = "" ]; then
	        echo "$0 <iso>"
	        exit 1
	fi

	if [ ! -f "$1" ]; then
	        echo "$0: cannot open $1"
	        exit 1
	fi

	growisofs -dvd-compat -Z /dev/dvd=$1
	cdcontrol eject

I know this is *very* lazy stuff, but it works, and I never change
a running system. :-)
