On all systems:
"obs_pad" pads the data of the last write operation of a DVD-R[W] DAO session
or BD-R session 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.
Whether it is applied automatically to BD-R depends on "bdr_obs_exempt".
"obs_pad" can be disabled by "no_obs_pad".
@*
"bdr_obs_exempt" exempts BD-R media from automatic unconditional transaction
end padding, provided that this padding is not requested by "obs_pad" and that
no stream_recording is requested. "bdr_obs_exempt" can be disabled by
"no_obs_exempt".
