the DVDs here are non-encrypted region-free. You can just copy them by dragging the VIDEO_TS folder onto your computer. check the md5s whenever you make a copy.

As for if the ripped video_ts folder being identical or not, you can check that using md5... see the "checksums demystified" link in my signature. But like I said before, you can just skip the whole dvdshrink step for the DVDs offered here.
