Howard,
The Oracle docs state that direct path insert only works when using the format Insert /*+APPEND */ into ... Select ... from syntax. Here is the reference from Oracle:
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96524/c21dlins.htm#11358

"Note: Direct-path INSERT supports only the sub query syntax of the INSERT statement, not the VALUES clause. For more information on the subquery syntax of INSERT statements, see Oracle9i SQL Reference ".

Is that not correct?
