.BI dvd_obs= default|32k|64k
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
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 systems
which show latency problems. The default depends on media type, option

.BI \--obs_pad
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.

There are reports that DAO sessions of a size that is not a multiple of 16
blocks abort on some Linux kernels and/or DVD drives.
