KProbe: Continually scanning past data burned

I am using a Liteon 1633S@ 1653 CS0P

I scanned using KProbe my recent burns and some reason it always reads past the disc end. I press the “check size” button and it tells me the size of the disc accurately (as how much I have burnt) but when it actually does the scans it goes past, and anything past that gives errors, as you can see the constant green.

Is this a drive problem? or burn problem anyone know? seen this before anyone?

The most common cause of this is that you didn’t close the disc.

Hmm my nero must be screwed up… or my dvd drive… thanks i’ll look into it.
