Interpreting Kprobe

could someone please help ?

A few months ago my Liteon811S started to produce “Bad” burns with firmware HSOR. I recently read that a number of people had had problems with HSOR so I changed the firmware back to HSOQ.

Having never used Kprobe I then ran a scan (attached) which had been burned with an NEC2500 and using Nero DVD Speed had given decent results with a 98% quality score.

So how do I interpret this KPobe scan ? Do I just ignore the massive single spike ?

any thoughts ?
