Из консоли диски можно записывать программой cdrecord (она же wodim). Для доступа к приводу используется интерфейс SCSI GENERIC (sg). Работать с программой рекомендуется с правами суперпользователя (root-а), поскольку иногда ядром ограничивается множество доступных SCSI-команд для непривелегированных пользователей. Сначала нужно узнать какое устройство в системе у нас соответствует пищущему приводу. Это можно сделать, например, следующей командой:
dmesg | grep -E "CD.*RW" -A 1 scsi 1:0:0:0: CD-ROM Optiarc DVD RW AD-7200A 1.05 PQ: 0 ANSI: 5 sr0: scsi3-mmc drive: 125x/125x writer dvd-ram cd/rw xa/form2 cdda tray
Здесь видно, что пишущему приводу соответствует устройство /dev/sr0. На него есть также симлинки:
ls -l /dev/dvdrw lrwxrwxrwx 1 root root 3 Июн 4 19:32 /dev/dvdrw -> sr0 ls -l /dev/dvd lrwxrwxrwx 1 root root 3 Июн 4 19:32 /dev/dvd -> sr0
Затем создаем iso-образ или берем готовый и записываем:
cdrecord -v -dev=/dev/sr0 -blank=fast /tmp/CentOS-5.2-i386-LiveCD.iso wodim: No write mode specified. wodim: Asuming -tao mode. wodim: Future versions of wodim may have different drive dependent defaults.

Для любителей графических интерфейсов есть k3b (обычно имеется в стандартных репозиториях) или проприетарный Nero.
