[arch-general] ISO broken? Unable to boot from ISO burned to DVD.

Hello, I've freshly downloaded the ISO from the Arch Linux homepage and burned with: # cdrecord dev=/dev/cdrom -dao PATH_TO_ISO Booting from this hangs with waiting for some /dev/disk/by-label/ARCH... device. After waiting for this I get to some kind of "recovery console" missing most tools. /dev/disk/by-label doesn't exist at all in this minimalistic shell. Is it possible that booting from a device "by-label" just doesn't work for a DVD drive at all? Any way to fix this? Thanks in advance Manuel
