As root - cdrecord -dev=/dev/scd0 -speed=8 -dao -pad -v whatever.iso You might need to change /dev/scd0 depending upon your system, that works for me with a SATA burner. If your iso is not sitting on a separate physical drive from / and /home, try not to use any apps while the burn is taking place. Don't use a faster speed just because your burner supports it, I've found that the faster the burn the more likely some drives are to reject it as a boot disk even when the burn process doesn't report any errors, not sure why. If all else fails and you have a second computer, you can burn the small boot.iso and mount the dvd image on the second computer and make it available over http. Then boot off of the boot.iso and do a network install. I frequently do it that way, as I don't see the point in wasting a DVD-R when the first thing I'm going to do after successful install is run yum update to replace a lot of the packages.
