Three out of the four DVDs I've tried burning today have stopped partway though the process with the message:
Code:
WRITE@LBA=[string of numbers and letters] failed [...] Input/output error
Twice, it went ahead and closed the disc with only some of the content on it, but once it told me:
Code:
CLOSE TRACK failed with SK=[string of numbers, letters, and slashes] Input/output error
This is the first time I've had this problem. I'm using tovid (from the repositories) and Hardy Heron.

I've seen this reported elsewhere with people using KB3, Gnomebaker, DVD-Rs, and DVD+Rs, but I can find no reasonable or definitive solutions.

Has anyone heard, or figured out, what the problem is?
