Please help. i'm not sure if the burn quality is good or otherwise.

All that shows is burn speed. It doesn't tell how good or bad the burn was.

No it shows the playback speed. The curve is more jagged than I like to see but it might be your system, not the DVD. The graph shows that that drive is having no problems reading the disc. I posted a graph of a really bad disc a while back:

Someone else may be able to give you an interpretation, but here's a scan I just did of some Taiyo Yuden 16X economy media. I believe I used ImgBurn to burn it and a Benq 1640 burner.

If I have a lot of hard drive activity going on while performing the scan I get a little noise like in avextraxjp's graph. Just a few bumps.

avextraxjp, on a mediocre burn the graph will start to drop down after the ~4 GB mark. The graph I linked to above is a total disaster.

Apart from the burn speed test posted above, I've conducted a Scan disc test which it scored a 100
I'll try to do another test without tasks running in the background.

On another issue, Why am I not able to run a Nero Disc Quality test on this particular brand of DVD+R?

It won't run on certain brands of drives.

Pioneer drives aren't considered reliable for scans anyway. If you use quality discs in a good burner, you shouldn't have to worry about burn quality. I never scan discs and never have playback problems.
