[Bug-xorriso] Problem with burning bd-re using xorriso-1.24 under Ubuntu 10.04

[Herb Radford]

The command  used was:
growisofs -speed=1 -Z /dev/dvdrw7=/u00/mybr.udf


The result of the burn attempt was:

.
.
20494811136/21000000000 (97.6%) @1.1x, remaining 1:47 RBU 100.0% UBU
37.5%
:-[ address@hidden failed with SK=4h/INTERNAL TARGET FAILURE]:
Input/output error
:-( write failed: Input/output error
/dev/dvdrw7: flushing cache
/dev/dvdrw7: reloading tray

The bd-re disc appears OK and can be viewed afterward but what was the
failure??
