# Adding to mkisofs:
#	-l		Does avoid the problem for shortish names like
#			DVDVOLUME1-A.VOB. but does not solve the problem
#			for names longer than 32 such as 
#			real_extremely_long_name_way_beyond_32-A.VOB
#			which long are emitted by vobcopy from DVD.
#	-dvd-video	Does not prevent the problem

# If mkisofs emits:
#	Using VDVOL000.VOB;1 for  /DVDVOLUME1-D.vob (VDVOLUME1-C.vob)
#	Using VDVOL001.VOB;1 for  /DVDVOLUME1-C.vob (VDVOLUME1-B.vob)
#	Using VDVOL002.VOB;1 for  /DVDVOLUME1-B.vob (VDVOLUME1-A.vob)
# as does /var/db/pkg/cdrtools-2.01_7 on FreeBSD-7.2,
# & cdrtools-devel-2.01.01a63,1 
# then your mkisofs would misorder vobs from vobcopy in a film/ movie,
# unless you manually take corrective action
