I usually figure out my own way of doing things. Half the time they're terrible workarounds but I think this is a simple and elegant way to rip DVDs (or anything) into AVIs that can be immediately edited. Of course there are advantages and disadvantages, and I'm sure I'll get a lot of flak for suggesting SUPER, but this is easy, very effective, and doesn't require any muxing, indexing, sacrificial offerings, or forbidden seal techniques.
Here's the tutorial! (assumes using standard definition NTSC DVDs)

Well, that's pretty much it if you can figure things out for yourself, but details if you want them:
1. Open SUPER. Set it up exactly as I have it set up above, except the media file and the "other encode options" on the left. You might have to double check the audio tracks to find out which one is the language you want (if you intend to incorporate some of the original audio in your video)
2. Click the M at the top and choose Export a SUPER Settings Profile
3. Now, every time you open SUPER, it will remember most of those settings, but you have to redo the audio settings each time because it always goes back to MP3 for some reason. If all the settings are wrong you can just load that Settings Profile again.
4. Right click the box below "Drop a valid multimedia..." and choose "add multimedia file". Choose your VOB (or any other type of video).
5. If it's not already open click the "other options" button to bring up the "other encode options" window.
6. Figure out the timecode for the clip. For my example, I want a clip starting at 6:20 into the VOB and lasting for 25 seconds, so I convert minutes to seconds using the calculator ([6*60=360] + 20=380) and leave a two second buffer on each end to make sure nothing is lost.
7. Right click the box below "Drop a valid multimedia..." and choose "output file saving management". Choose where to save the file.
8. Click Encode (Active Files).
That's it! The resulting file will work immediately in something like Premiere, and doesn't require preview rendering or anything messy. You might have to have your editor convert the aspect ratio but that's it.
Advantages:
Easy process, few steps involved
All done with one program
Leaves you with just the clips you need, speeding up the editing process
Gives you DV AVI files, which are designed for editing with no discernable loss of quality during conversion.
Disadvantages:
Can be time consuming to find the clips, determine the timecodes, and rip them.
Resulting clips (DV AVI) use around 5MB/s of space, but if you have a modern hard drive and only get footage you need this isn't a huge problem
