What I had done was
mkisofs -o /Backup/mybackup.iso -R -J -l -v /Backup/amandatapes/Dailys/slot9
then
cdrecord -v -sao dev=cdrom -data /Backup/mybackup.iso
Towards the end of the output was a warning message, but then it seems to say
that it completed satisfactorily.

I'm a bit suspicious of the write speed. Whenever I have burned DVDs on the
same-model drive on this box I have always used 2x. I'm surprised that this
drive can do a DVD at 6.9x. Perhaps the command should have a speed limiter
inserted.

It's the all-too-common puzzle of two installations, nominally doing the same
thing, but finding that one is fine and the other isn't. A real frustration.
One thing I haven't tried, and will do today. I will copy the .iso file onto
this box and try k3b's 'burn a dvd iso image'. I have used it several times,
so I know that there isn't a problem with the software on this box. I'll
report back.
