Aloha JP,

This is what I use on FreeBSD from the command line to burn DVD's.
I have used it on FreeBSD 8* for a while. (Simple and it works.)-

dvdburner.doc
DVD+R burner Setup and operation

 From sysutils/dvd+rw-tools
Intall the DVD port

# growisofs

( used the following from all the suggestions and it worked with Manolis 
  DVD p1 7.2)

1st>  Put hw.ata.atapi_dma="1" in the /boot/loader.conf
2nd> Put apticam_load="YES" in the /boot/loader.conf

(That 2nd 18.7.2 instruction is not clear in the Handbook section and 
should be added.)

Then> Run # growisofs -dvd-compat -Z 
dev/cd0=/usr/home/alp/FreeBSD_7/7.2-RELEASE-p1-i386-disc1.iso
(all on one line)

Then> Use  cd0 as a DVD burner and make the DVD-R

I tested the DVD on a spare box and it installed just fine.
