Hearsay about DVD-R/DL (Dual Layer) :
DVD-R/DL can assume profile 0015h DVD-R Dual Layer Sequential which is supposed
to behave like DVD-R or 0016h DVD-R Dual Layer Jump which has no counterpart
with DVD-R.
A half-sentence in mmc5r03c.pdf 6.3.3.3.3 might indicate that closing a session
by 5Bh CLOSE TRACK SESSION Close Function 010b overrides the multi-session bits
in mode page 5.
growisofs applies this function in case of not DAO, though. A comment in
growisofs_mmc.cpp states: "// DVD-R DL Seq has no notion of multi-session".
I am not reading this from the specs - but not explicitely the contrary either.
For now libburn will close the session but there is a macro prepared in
libburn/write.c Libburn_dvd_r_dl_multi_no_close_sessioN which will suppress
close session if multi-session is demanded.
