what i want to do is copy a dvd movie on to my computer which im guessing will probably be maybe around 8 gigs and instead of compressing it to burn on 1 dvd i want to put the first half of the movie on 1 dvd and the second half of the movie on a second dvd. by doing it this way the quality of the movie will be identicle to the original but the only bad thing is the movie will be on 2 dvd's. how do i do this?
