ChopperXP is neat. I hadn't tried it until now. That faq seems to imply that it'll decrypt DVDs. But, while it reads one of my unencrypted DVDs directly, it then freezes on an encrypted one.
So if it won't read your's directly, rip it with Dvd Decrypter first. Follow that part of ADM's editing guide, with one exception - don't put a checkmark in the "Enable Stream Processing", so you can rip it to vob.
You can convert the vobs to avi with VirtualDubMod. It can also clip the VOBs to AVI. (Use the slider to find the good parts of each vob, mark the beginning and end with those two buttons on the right - the ones with those arrow-with-half-arrowheads symbols).
I'd save them to Huffyuv (lossless), before converting them to wmv (or another codec). That'll give you perfect AVIs to experiment from. Right-click the .inf and select "Install". Select the codec in Virtualdubmod: Video -> Compression. Virtualdubmod (or Virtualdub, or Virtualdubmpeg) can also convert to any other codec you can get the compression codec for. (Not wmv, Quicktime, or Real Media).
I haven't made wmv's yet, so I can't tell you much about it. Windows Media Encoder.
I'm not sure if mpeg1 comes with Windows, or needs a codec installed, to play it. TMPGEnc makes mpeg1's for free, or mpeg2's on a 30-day-trial.
Someday, I'll make a post that doesn't need to be edited...
