What version of CD-DVD Speed are you using? I'm concerned that you selected 4x but 12.37x is shown at the bottom right.
There's nothing so terribly wrong with those scans. The KProbe one is pretty good and well within spec. The clump of PIF's at the 4gb is a little concerning but nothing out of the ordinary.
And the TRT is fine.
There's been some debate about the value of DQ scanning on it's own. TRTs show that the disk reads well and there's a suggestion that high speed DQ scans have some merit.
I'll add that I'm no expert on this but I'm sure that others more technically knowledgeable will have some input.
