Hey, I finally got a reply from the Customer Service rep. Turns out that the deluxe sets are exactly the same, so you should be able to play the DVD!

Okay, thanks for the info! If you find something out, could you please let me know? I'm really worried about it. Too much money to not be able to play the DVD!

Hey! Nope, haven't gotten anything in return. As soon as I sent the email I got the usual 'thanks for your email, we'll reply within 1-2 business days', so it might be a while before I get something back.

Hey I saw your post about accidentally ordering the .mu boxset instead of US. I did the same thing. Did you find out anything?
