VTS_TMAP discontinuity flag

Hi all,

It's not clear to me when this flag (bit 31 of each VTS_TMAP entry) should be set.
On mpucoder's site it can be read
"bit 31 set if VOBU time codes are discontinuous with previous"
which is not clear to me.

MuxMan does not mark any discontinuity in TMAP table (testing the case of one PGC with several chapters) but, looking what IFOEdit does, seems IFOEdit marks as "discontinuous" the last VOBU in the table for each cell, including the last one

Looking into a couple of originals, I've seen the same that IFOEdit does: The bit is set in the last VOBU in the table of each cell.

Could anyone clarify this point?

EDIT: Found other original marking as "discontinuous" the first VOBU of each cell. But, even in this case, the last entry (which is the last VOBU of the last cell) is also marked as discountinuos.
