Update: Making it work is more complicated than that. Omitting the
"-dvd-compat" switch is not on its own enough to make it work.
First it is necessary to attempt to burn using dvdrecord. This fails
with the output posted above, but it does have some effect which allows
an immediately-following invocation of growisofs on the same blank to
succeed.
So the winning sequence is:
$ dvdrecord -v driveropts=burnfree speed=1 dev=1,0,0 -dao foo.iso
(fails with above output)
(leave blank in drive, do not perform any other dvd commands)
$ growisofs -Z /dev/scd0=foo.iso
(works).
Using growisofs without the preceding dvdrecord invocation produces
"unrecovered read error" messages initially but then appears to get itself
going and start working; however the resulting DVD gives "Input/output error"
when trying to read it.
$ growisofs -Z /dev/scd0=foo.iso
Executing 'builtin_dd if=foo.iso of=/dev/scd0 obs=32k seek=0'
:-[ PERFORM OPC failed with SK=3h/UNRECOVERED READ ERROR]: Input/output error
