I'm trying to write an image onto a dual layer DVD+R disk using growisofs:

growisofs -dvd-compat -Z /dev/dvd=image.iso

On my FC6 Myth box, it consistently gets a third of the way in before
failing:

The media I'm trying to use is Datawrite 2.4x 8.5GB DVD+R DL.

My image is on an ext3 formatted partition on a SATA disk. I've tried
specifying -speed=1 (though this doesn't seem to make a difference).

Does anyone have any ideas? If it fails in this way is there any way of
restarting it, or is the disk only good for the bin?
