Not sure about this guide?

Umm, I feel like a real dumby for asking but could someone explain in better detail about this:

Okay, I get that you need to scan for bad frames and correct the audio/video sync first, but how do I know if I have "bad frames" and if I do how do I correct them? Also, the reason I'm looking for this is to fix audio/video that is in sync most of the time, but in tiny parts seems not quite right is that audio drifting? It says if it is wrong to begin w/, this method probably won't help. So what good is it if what you have isn't perfect and if you had something perfect then what do you need this method for? I'm confused!
