I see: the file with discontinuities is virtually split at the
discontinuities, something like that:

file title.vob
subfile 0 56401920
start_time 0

file title.vob
subfile 56401920 864829440
start_time 1:39.900

file title.vob
subfile 864829440 921231360
start_time 23:00.150

That could work indeed, and would not be very hard to implement. But it does
not handle the 33-bits wrap, though, due to the interleaving problem.
