I use Xilisoft DVD Ripper 4. It's a pretty decent ripper, and you can rip into almost any format. It's pretty easy to use, as well, but its not freeware. I would recommend ripping a DVD (the main movie/bonus parts, not menus) into either DivX AVI or XVid AVI.
And WMP can rip music, just rip it into MP3 format on the highest quality setting. You can also use JetAudio player, which has a built-in ripper, and audio/video converter.
