Is this a good scan?

I am trying to figure out KProbe. I am using the default settings, except I am making sure it reads a 4X. Is this okay? Can you tell me how to determine what’s a good disc or a bad one? I just got done scanning a disc and would like you to tell me if the disc is doin good or what?

I just scanned a dvd that acts like crap when i play it in my stand-alone. It skipps at the end really bad. This was made when I had FSOJ firmware. I went to FSOF and the first one I posted plays without a single hitch! I am guessing this one look MUCH worse?
