Don't know about Linux, but on FreeBSD you can use the growisofs tool from the "dvd+rw" tools collection (ports/sysutils/dvd+rw-tools). The syntax is simple: growisofs -dvd-compat -Z /dev/cd0=dvdimage.iso (/dev/cd0 is my dvd drive.) I think you can also use the burncd tool that is part of FreeBSD's base system, but I haven't tried to do that. growisofs works perfectly fine for me (it also handles double-layer media (8.5 GB) correctly, BTW). You cannot use dd for that purpose because dd doesn't have special knowledge about the recording process, e.g. it doesn't know how to determine the laser power, it doesn't know how to enable burn-proof, it doesn't know how to fixate a CD or DVD, i.e. the session won't be closed properly, and so on. That's why a special-purpose tool is better suited to handle recording of CD and DVD media. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
