To my experience, cdrecord and its derivatives do
not burn DVD sucessfully if not option -sao is given.
Does growisofs burn those media properly ?
growisofs -Z /dev/sr0=./flt-cnc3.iso

The program tries to close the session by a
command described in MMC-5:
"126.96.36.199.5 Close Function 101b: Finalize with Minimal Radius"
This gesture itself looks appropriate according to
the specs. My own program cdrskin would use the same
(if some wealthy tester risks DL media and sets argument
One could change the function to 010b which is probably
what growisofs will do because it is reluctant to finalize
+R media at all. (cdrskin will use function 010b if option
-multi is given.)
One could also change to function 110b (which is deprecated
in MMC-5 188.8.131.52.6).
But i assume the problem is rather about some SCSI command
prior to the failing one. Either a setup command from the
start of the session or a missing command at the end.
Thus the hope that option -sao might help.
Well, exploring DVD+R DL is expensive. No dummy mode.
Have a nice day :)
