There may be other unforeseen breakage primarily in the handbook portion of the wiki.
The Table Of Contents section of each "PC-BSD® Users Handbook" page may be the best workaround.
Using growisofs/dvd+rw-tools in FreeBSD
If you are familiar with the Unix command line, you can install the sysutils/dvd+rw-tools port and use that to burn the DVD. Once the port or package is installed (see the FreeBSD handbook if you are unfamiliar with the process) you follow the following steps:
# Place the blank DVD into the drive (I'll assume it is /dev/cd0) # Issue the command: growisofs -Z /dev/cd0=PCBSD8.1-x86-DVD.iso # Eject the DVD once growisofs is complete
You may need to have the ATAPI_CAM kernel option in your kernel to successfully do this if you are burning to a DVD drive that's connected via the ATAPI interface.
