You need to download a dvd extractor to remove the contents of your disk to the comp and convert the files using a dvd converter.
There are many threads on the subject.
Roughly
First stage decryption.
4 protection methods
CSS: not the web coding but a very weak copy protection. Countless tools to do it and most commercial DVDs use it. Low buget/small time films tend not to as it is so weak and quite expensive.
Macrovision:
This stops people copying via video player (assuming their player supports macrovision- they managed to get it worked into the spec and maybe even law so most do. Older and "chinese" players may lack it.
Region coding.

You are R4, normally get stuff later but R4 is some of the best and often has the best extras.
US is R1, Europe and Japan are R2
R5 is Russia and indian subcontinent. Notable often for getting DVDs before the rest of the world (usually only a russian dub if it does happen), not usually very high quality though as they are quick and dirty transfers.
Some earlier DVDs had so called region code enhancement to detect region free players, this is not used any longer.
Method 4: corrupt sector, sony's ARccOS being the most notorious but many other companies have had a go at it.
This is what poses the problem to older tools but I still advocate them.
Sidenote there is a 5th thing called UOP or user operation prohibitions (there are a few other names for the same thing). Ever noticed you have to watch the adverts/anti copying junk? Now you do not (one of the nice things about dvd43 and co)
Decryption tools.
DVD Decrypter (author now does IMGburn if you use that), taken down quite some time ago but makes short work of the first 3 methods so I suggest having it in your collection. Also the most customisable.
ripit4me. A frontend to DVD decrypter that can deal with most corrupt sector methods. Also taken down and will fail on some of the newest corrupt sector methods but worth having around.
Both should not be that hard to find.
AnyDVD, DVRegion +CSS free, DVD43. These are decryption methods that sit in the background and do it in realtime. Useful but not my preferred way. DVD43 is the only freeware and it has a reputation for not being that brilliant, having not used it in several years I am reluctant to say.
DVDFab. A commercial decrypter with a cut down (but not as far as protection is concerned) free version.

These will generate a DVD folder on your hard drive. I assume you know about single layer and dual layer already but if not single layer 4.35 gigabytes, dual is double that (8.7) and the reason you sometimes get a pause halfway through a film.
There are some tools that can do more than decrypt but they often fall flat on corrupt sector discs.
From here there are all in one methods. If you want those go hunting for the threads, the following method is what release groups tend to use (although I dare say you can probably use a bit higher bitrate, 350 megs for a 40 minute show is too low for my liking).
Stage 2:
getting it ready to serve to something else.
I use DGDecode.
http://neuron2.net/dgmpgdec/dgmpgdec.html
Stage 3. Encoding.
I use megui but you can use virtualdub. The good thing about avisynth is that is it also a very powerful video editor*)
http://x264.nl/
avidemux is something I have been playing with and can happily recommend:
http://fixounet.free.fr/avidemux/
Probably a bit simpler than megui but lacks power because of it (still can make great quality AVI files mind).
*DVDs are often interlaced meaning you have may to deinterlace them (it gets a bit more complex than that but roll with it for now). There are hundreds of tools/methods of varying quality and speed, DGBob works for me: http://neuron2.net/dgbob/dgbob.html
Stage 4 (if necessary, muxing it all together).
You said AVI so I suggest megui.
If you want MKV (soft subs, dual audio) then I suggest mkvtoolnix (mkvmerge)
http://www.bunkus.org/videotools/mkvtoolnix/
Stage somewhere in the middle.
Subtitles.
The two most popular types are srt (subriptext) and ASS/SSA (advanced substation and the older substation alpha).
Srt is basic text.
ASS is more advance XML like encoded text capable of the fancy karaoke intros and whatever else.
DVDs on the other hand are just pictures so you will need to turn them into text, OCR by means of subrip is the most common:

OCR is not an exact science so Subtitle Workshop is worth having around:
http://www.urusoft.net/products.php?cat=sw
If you want to rip DVDs to DVD5 (single layer) then there are also many tools.
DVDShrink (has limited ripping capabilities when it comes to ARccOS and the like) is pretty good.
For any serious work (read lots of compression needed) then DVDrebuilder is good.
My suggestion now is head on down to http://www.doom9.org/ and the forums there.

thanks for that, but now i'm still just as confused...
is there no way to just take the one title i want on a dvd and rip it straight to an .avi?
or is the vlc ripper the quickest way to go?

Try using Handbrake [http://handbrake.fr/] It's an open source DVD to mpeg4 ripper. It probably does other formats, too.sphere9 said:
I usually use Format Factory [http://www.formatoz.com/] to convert the file to whatever I want after. (Again, free)
Good Luck!

@Xdqwerty, to answer your question, they're a fusion Brit-pop/J-pop/electronic band with a woman vocalist. Flamingo is hands down their best known song but they've got a ton of other really good songs+1 -

For example, one of my other favorite songs from them, with some massive house music influence -+1
