There's a few things you'll want to look for, most notably PIF clumps higher than 4. The bottom graph is used for PIF, top is PIE.
Your results look fairly poor for that media. If you look at the total under PI Failures, yours is over 4000, and there are several large clumps.. Nothing that would make the media unreadable, but fewer is always better. Look at the other MCC 004 scans around the forum and you'll know how yours compares.
PIE levels are less important, anything higher than 200 is considered bad, but again, fewer is generally better.
The TRT graph was a good idea, notice how there's a couple slowdowns, but since they're small it's hard to tell if it's because of a bad burn, or something running in the background on your computer hogging bandwidth. Some more info would be helpful, such as burn speed, burner firmware, etc. You could try burning at a lesser speed to improve results.
As far as software, Nero CDSpeed is mostly the norm around here, but they all display the same information if you know what to look for, so you can't really go wrong with either. But for the sake of simplicity, many prefer CDSpeed especially "newbies" who don't know exactly what they're looking for.
