If you however want to do something _not_ illegal, there are quite a few commercial tools that will allow you to transform a DVD's movie (not the subtitles, though, AFAIK) into an SVCD. Davideo does that for example.

Keep in mind that if you're using VCD, you can't have subtitles the way a DVD does. The subtitles will need to be burned onto the video track, so you won't be able to turn them off or have multiple subtitle languages.
Also, of course, the video quality will suck with VCD. VCDs use MPEG1 video at pretty low resolutions, so expect quality MUCH worse than DVD.
If your DVD player support MPEG4/Divx, you may want to burn it that format, which will look a helluva lot better than a VCD. To find out if your DVD player supports this, look it up at http://www.videohelp.com/.
