Well, I used PowerDVD, and it does play it, but there is noticeable slowdown and freeze-up at the end of episode 2. This is probably a quirk of the computer's DVD drive, and probably doesn't have anything to do with the copy protection.

There are some DVDs it can't handle, like End of Evangelion, (it freezes/slows down around the part where Lilith comes off the cross) which my friend's DVD player handled perfectly fine.
What about a PS2? I don't have one yet, but I am saving up money to get one. Would the copy protection matter to the DVD drive of a PS2?
