[Libburn-hackers] libburn never finishes burning DVD image

I have a user who reports that burning a DVD image never finishes[1].
I had him try cdrskin, and it exhibits the same issue. Can we get some
help here?

An excerpt from the bug report:

I've got the DVD writer PIONEER DVR-216D and use Verbatim DVD-R 16x discs which
can be written at 20x with this writer.

The problem happens with cdrskin, too. It first burns normally, then it says
"thank you for being patient", counts seconds until infinite and does nothing.
If I press Ctrl+C it says it waits for the drive to finish but nothing happens.
The only thing which helps is kill -9 and reboot.

This is the console output:

$ cdrskin -v dev=/dev/dvd0 dvd.iso
