Block size for CD/DVD is 2K, so to get the best speed/reliability, you should use bs=2048

To make it all happen you need:
in kernel
Code:
options CD9660 # ISO 9660 Filesystem, because you want to read them ;)
device atapicd # ATAPI CDROM drives
device atapicam
device cd # nessacery for dvd's
device pass
device scbus
options MD_ROOT
device md
and permission to write to /dev/acd0 /dev/cd0 /dev/pass1

One should also have
options UDF in order to read DVDs with files larger than 2 GB on them, or to burn DVDs with files larger than 2 GB. I believe there are extensions to cd9660 to allow for files larger than 2 GB, it's more reliable to use UDF.
The
pass device number will also depend on the order that SCSI devices are enumerated by the kernel. To determine exactly which one it is, one can use
camcontrol devlist
Excellent post. There's some info in there that I hadn't known, as I've been using K3B for so many years now.
Nice little cheat-sheet for when I want to burn something remotely. Thanks.
