Extracting Digital Video from LaserDiscs?

americanatavist asks: "I was wondering how feasible it would be to digitally copy LaserDisc movies to DVD. Clearly this would require the standard suite of tools to make a DVD. What method would yield the maximum level of quality? Is it worth the effort to find a means of extracting the digital information using an LD-ROM drive, or would the S-video from a regular LD player suffice?"
