That's DirectCD that does the UDF stuff. It's the program that allows the
CDR(W) to be written to as a drive letter under Win32. It will "format" a
CDRW for UDF but _not_ a CDR. It will _still_ write UDF packets to the CDR though
but only enough to hold the data being written. CDCreator, OTOH, does
proper ISO9660 CD mastering and (AIUI) _doesn't_ do UDF. A UDF CDR(W) can
be "closed" into ISO9660 (Mode 3) by the addition of a toc at the
beginning but this is not necessarily compatible with other OSs.
