Simply reencoding and creating a DVD at a lower bitrate isn't the best idea since MPEG2 isn't the most efficient codec around. You either won't save that much space or will lose quality pretty soon. There are a few relatively easy to use GUI Tools around (ogmrip comes to mind), but they are somewhat limited in options. One tool that has quite a few options (but therefor requires some knowledge and reading on your end) is dvdrip. All of these are best used for encoding to xvid. But there is a new star on the codec horizon, and that's h264. Takes a lot of CPU cycles to encode (10-12h on an opteron 148 for a 2h movie with high quality settings here), takes more CPU power than xvid to decode (Though that shouldn't be as bad as encoding) but gives you the same quality as xvid with half the bitrate. The best way to encode this is with mencoder, their homepage has some good information and the mplayer man page has the rest.
