Note that growisofs attempts to split at default layer boundary.
Meaning that the image is exactly as large as full media capacity, right?
Actually, the image happily.iso is less than full capacity as I
understand it. I burned the image happily.iso without the -dvd-compat
and then did a mount and
~$df
/dev/cdrom 7443456 7443456 0 100% /mnt/cdrom
It is my understanding that the the DL holds 8.5GB so this is lower than
full capcity?
Can you try smaller image so that growisofs would try split at lower
value? If it works, then it's just specific firmware glitch [which can
be worked around in next version].

As you can see from above, I got a similar result. Note that I used
Imation +R DL instead of Verbatim +R DL media this time. (I ran out of
Verbatim).
As I stated above, if I don't use the -dvd-compat option, the dvd burns
without any errors and will play on my Shinco dvd player but not my
Yamaha
dvd player.
It should be noted that if image is exactly as large as media
capacity, then the recording performed without -dvd-compat is
identical to one performed with [at least according to specification].
Varying results are more likely to be caused by limited capability of
second player to play DVD+R DL in general, rather than how this
particular recording was performed. A.
Thanks for this information. I am slowly beginning to understand. Thanks
for your response.
