.BI -isosize
The next track following this option will try to obtain its source size from
the header information out of the first few blocks of the source data.
If these blocks indicate an ISO-9660 filesystem then its declared size
will be used under the assumption that it is a single session filesystem.
.br
If not, then the burn run will be aborted.
.br
The range of -isosize is exactly one track. Further tracks may be preceeded
by further -isosize options, though. At least 15 blocks of padding will be
added to each -isosize track. But be advised to use padsize=300k.
.br
This option can be performed on track sources which are regular files or block
devices. For the first track of the session it can be performed on any type
of source if there is a fifo of at least 64 kB. See option fs= .

.BI msifile= path
Run option -msinfo and copy the result line into the file given by path.
Unlike -msinfo this option does not redirect all normal output away from
