I'm trying to write double layer DVDs on my TS-L632C DVD burner.
It has always handled single layer DVDs fine and this is the first
time I have a problem. What I get is this...
Executing 'mkisofs -dvd-video -V DVD /home/abc/dvd | builtin_dd of=/dev/sr0
obs=32k seek=0'
Setting input-charset to 'UTF-8' from locale.

:-[ SEND DVD+R DOUBLE LAYER RECORDING INFORMATION failed with SK=3h/POWER
CALIBRATION AREA ERROR]: Input/output error
growisofs still does not write completely readable error messages :-(
This is an opinion. The fact is that whether or not and when power
calibration is performed is left to firmware discretion. "Not" refers to
fact that firmware might choose pre-defined profile. "And when" on the
other hand varies from firmware to firmware, some firmware start the
calibration procedure at a WRITE command, others at SEND DVD STRUCTURE
with DVD+R DL layer break position. As result power calibration errors
get accounted to either of these commands. Christian, as for error
interpretation and advice, see Thomas' post.
I recommend you to use cdrecord instead of growisofs.
Cdrecord will tell the drive to do laser power calibration
cdrecord does not do that to DVD+ media. A.
