In this test I hacked lines in ready_media_for_file() to display the results of the query within that function. This was tested against America's Army.msi and I verified the contents the Media table in ORCA.  This query is SELECT * FROM MEDIA WHERE LastSequence >= 1 ORDER BY LastSequence, and it is returning LastSequence of 0 on DiskId 22 accessor.cab, and zero is not greater than 1.
