players to recognize a DVDR disc because of obsolete firmware.
In my case I have to load my clients' audio files from DVDRs almost
every day and I'm not alone in finding them to be far less reliable than
CDRs. How exactly do you define "superior?"
I'll not attempt to answer for Jerry, but I will say that a poorly
written DVD of any flavor is even less likely than a flaky CD-ROM to
give a clean file. Perhaps in part that's a consequence of the greater
capacity, often inducing people to write larger files than needed.
A good DVD blank written at 4x gives excellent results. At 16x and
above, I've had problems which I suspect at times derive from buffer
underrun protection being invoked so often. That's quite noticeably an
issue if a DVD is copied on the fly; I've a four-bay duplicator which
even at 4x invokes buffer underrun protection several times near the
beginning of the disc.
