If the track source delivers less bytes than announced then the missing ones
will be filled with zeros.

.BI --tell_media_space
Prepare a recording session, do not perform it but rather inquire the
maximum number of 2048 byte data blocks which may be written in
the current state of media with the prepared setup. So this option disables
recording of data. It does allow blanking, though, and will measure space
afterwards.
.br
It is not mandatory to give track sources but their nature may influence
the available capacity. So for most realistic results one may set up
the full burn session and add --tell_media_space. But if one has to expect
a cdrskin version prior to 0.3.3 no track source should be given in order
to start no involuntary burn session.
In this case set at least -sao or -tao explicitely.
.br
The result gets printed to standard output.
This option redirects to stderr all message output except its own result
string and eventual output of -msinfo.
.TP
.BI write_start_address= byte_offset
Set the address on media where to start writing the track. With DVD+RW or
DVD-RAM byte_offset must be aligned to 2 KB blocks, but better is 32 kB.

Option is still immature and likely to change.
Problems arose with sequential DVD-RW.

Expand the last track of the session to occupy all remaining free space on
the media.
