+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.

+If not, then the burn run will be aborted.

+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.
