Posting this here to help those that like me are probably gonna have trouble figuring out the proper way to remove the discs from this blu ray set. Suffice to say i have never seen disc holders like this before.
You'll notice two flexible plastic arms at the bottom of the disc holder. Those are the key to removing the discs properly.
What you'll want to do is put your index finger in the center ring of the disc and carefully pull downwards causing those plastic arms to flex and then gently pull upwards to pull the disc out.
I would be carefull not to put more pressure than needed on those flexible plastic arms. I can imagine that if one of those break it will never hold the disc securely again.
I would have gladly paid 10 extra dollars to have a more traditional disc holder for this set.
