Just FYI, here are The Guides
for reference, and here is a GlossarySummary/Explanation [as best as I can put it]
-after ripping a DVD, you have a .VOB file(s) that contains your footage
-unfortunately these cannot be read quickly or accurately unless we have extra information about the footage
-dgindex does this by scanning the .VOB ahead of time and gathers information into a .d2v index
-it's like making the index to a textbook (you'd need one to find anything quick and accurately)
-this index is gibberish to most programs except avisynth
-now, avisynth is tricky to explain because it is not a typical program with a GUI (like a window with buttons).
It runs in the background of your computer, and
1.Takes input video/information/footage
2.Interprets the video information
3.Manipulates the footage how you want
4.Serves the manipulated footage to another program (like VirtualDub or AvsP)
So... you never really get to see avisynth
but you can see the manipulated footage it produces
in another program.
The Guide's explanation can be found here:AviSynth and AvsP - What they are, and why you need to use them too!
Here are some ways avisynth can manipulate your footage and prepare it properly before you edit:
- deinterlacing (with the help of the info. from dgindex)
- decimate; change frame rate for smooth motion
- crop black borders off footage
- resize your footage to the proper aspect ratio
- clean your footage of artifacts, grain, macroblocks, aliasing, halo's, rainbowing, etc. (if needed)
- much much more...
-avisynth achieves this by applying various filters to the footage;
-the filters you choose are determined by the lines you type into an avisynth script;
-a script is basically just a text file with the extension changed from .txt to .avs
-vdub (VirtualDub/Mod) or AvsP are common programs used to open these .avs scripts so you can see if avisynth is doing what you want it to do
-They are also the programs that use various codecs
to compress your filtered footage to a format that can be read by your editor.
-After going through this process, you can edit with the best footage possible

it just requires a lot of time and reading
Granted, they could probably use better organization, but if you click that link you'll see that it is kind of difficult to organize that amount of information without over-generalizing concepts. And it would require an even bigger overhaul than The Guides have already gone through.
... you just have to give it some time. LOTS of Time.
If you need any further explanations feel free to ask.
Specific Questions are good.
