Ive been ripping dvd's and software disks for personal backup and storage on my server or to use on my laptop when traveling. I personally love using
Ultra ISO, its free via download. What it does is rips a complete image of the dvd, meaning full size image (up to 4.8gig) only thing is you need another program to read/convert the iso, for this i use
daemon tools which emulates a drive on your computer, or multiple drives. Then you need to convert the iso into a video file and compress it. as of yet i havent had to do this step, once i get my Iphone i will update this on how i go about compressing for veiwing on the iphone.
