Because 4K video is coming out and blu rays are a dying format, I'd like to digitize my entire DVD and BD movie collection. I'm getting sick of upgrading video players, and buying new versions of the same movie. iTunes, and other companies are not giving us that option to rip our movies , so I was wondering if any of you have attempted it, and what programs are you using to do it. Also, is there a universal format like mp3 was for audio? Is it easy to add subtitle and commentary tracks?
