Not sure what DAO mode is,
Disc-at-Once (DaO). In the original and _true_ definition, it means the laser is _never_ turned off. I.e., it's mutually exclusive with "burn proof." True DaO can increase both media longevity and pre-2004 DVD player compatibility. True DaO requires you drive the record with a character device (byte-by-byte). Today, most DVD recorder drives are driven by block device and easier to use software. So DaO means something entirely different these days. This is a mega-simplification of a very long story with literally dozens of variables -- drive/media type, firmware/command approach, etc... I've been using DVD-RAM for optical archiving since 1997, and DVD-R for similar duties since 1999. And there's reasons I _never_ use CD-RW, DVD-RW and DVD+RW.
