629222reserved

Only 4 of the bits of the ILVU flag word are used, the top 4 of the first byte. They are:
bit 15PREU flagset during the last 3 VOBU preceeding an interleaved block.
note: the 3rd preceeding has the Unit_Start bit set for a value of a0, the 2nd preceeding has only the PREU bit set for a value of 80, and the 1st preceeding has the Unit_End bit set for a value of 90
bit 14ILVU flagset for all VOBU in an interleaved block
bit 13Unit_Start flagset for the first VOBU for a given angle or scene within a ILVU, or the first VOBU in the preparation (PREU) sequence
bit 12Unit_End flagset for the last VOBU for a given angle or scene within a ILVU, or the last VOBU in the preparation (PREU) sequence
