DVD burning in FreeBSD

Enable atapicam:
If you bought a cheap IDE DVD recorder you need to enable atapicam before you can burn DVD with FreeBSD, so it can be accessed through the SCSI subsystem. You could either compile a new kernel to support or simply add the following line to your loader.config.
Add:

atapicam_load="YES"

to: /boot/load.config

Compile makeisofs:

cd /usr/ports/sysutils/cdrtools/
make install clean

Compile growisofs:

cd /usr/ports/sysutils/dvd+rw-tools/
make install clean

Burn the DVD:

cd growisofs -dvd-compat -Z /dev/cd0=dvd.iso
