Best way for me has been to use DVD shrink. Get that along with a program called anydvd. anydvd "tricks" (lack of better word) your drive into not reading the encryption. normally with those two porgrams it took me about 15-30 mins to rip a dvd to the harddrive.
i keep getting an error with my dvd shrink.. i dont know whats wrong
same here, but only with newer dvds like less then a year old. dvd shrink willl probably release a patch soon.
