I have just written two DVD-R using K3b, which I have been using for years, I have once had some bigger trouble with K3b, there is a thread on Forum, but else it just seem to work. I have however just received very similar message as posted here. When the second DVD failed I discarded them both without testing but I have just re-covered them from the trash after having read the postings here.
The two DVDs were an attempt to write KDE 2012.12 as a backup copy. Unusual for me I actually checked the md5sum before write exercise, no problem. I have been lax with md5sum checking as they always seem to match. The first DVD write reads ok in optical drive, I assume the second also do, that is drying on the clothesline at the moment.
I did make a copy of K3B log for the first write:

Perhaps this is a clue for somebody. Not for me as I normally don't look at the log so I don't know what it should look like. I will check if it can run.
Edit:Well it booted fine and runs as I am using the LiveCD to post this addition. In that case I expect the drying version will be ok, one of the grand kids were told to scrible all over the second write to make sure I knew it was a dud. fortunately he did it on the top side so I have washed it off again as the artwork did not stick well.
