Linux specific:
Set the number of bytes to be transmitted with each write operation to DVD
or BD media. Tracks get padded up to the next multiple of this write
size. A number of 64 KB may improve throughput with bus systems which
show latency problems. The default depends on media type, option
stream_recording=, and on compile time options.
or BD media. With most write types, tracks get padded up to the next
multiple of this write size (see option --obs_pad). A number of 64 KB may
improve throughput with bus systems which show latency problems.

@c man .TP
@item --obs_pad
@kindex --obs_pad write transaction end padding
@cindex Transaction size, set, dvd_obs=
Pad the data of last write operation of a DVD-R[W] DAO session or
stdio: pseudo-drive up to the full size of an output chunk.
This padding has to be applied automatically to the other DVD and BD media
types, where it causes e.g. ISO images to have trailing unclaimed blocks.
.br
Use this option if there is the suspicion that DAO sessions abort with
your kernel and/or DVD drive, if their size is not a multiple of 16 blocks.
.br
This option may also get enabled at compile time of libburn.
