I erroneously scanned a Philips DVD+R 4x with speed set to max and got the result as shown in the attachment. (BTW, the current speed slowly crawled from 2,8x till 6,0 at the end.)
I then rescanned with the recommended speed of 4x, and got a complete different result as can also been seen from the attachment (and which is in compliance with KProbe 1.1.29).
Can anybody explain why these results are so different? And which result reflects reality?
