The problem with all of these tools is that they are not CD burners, they are
user interfaces to the real tools. And they assume that what you want to burn is
a *file* rather than an *image*, so they create an ISO9660 filesystem holding
the file and burn that. Which doesn't work. If you care, try to mount the
non-booting CD and see if it mounts as a filesystem with one big file in it.
You also might want to install the real cdrecord program, actively maintained by
the original author. Works far better for me, but you have to compile yourself.
Do you have wodim installed?
wodim-1.1.10-1.fc13.i686
install it and run it as root:
wodim -v dev=/dev/sr0 speed=4 (or whatever) imagefile.iso
and sit back or take a long coffee break.
It WORKS!
Be happy! :)
PS: ... I have found that burning at high speeds produces dvd's with
checksum errors.
on my 8X dvd burner, I always burn DATA dvd's at 2X, but video
and audio at 8X.
