He can't watch it. Some of the video is just not there. Layer 1 doesn't contain certain titles of the DVD and one title (epidose 2) stops half way thru and goes to TCM. Anyone who says a person who has bought this disk can "watch it" is missing the point that the buyer is not getting what he paid for.
Having said that, this is the first time I've seen such a freaky thing happen.
As I said before, nothing can successfully rip such a DVD.
