Well after becoming a some what HD DVD case expert I found out a few things when it comes to these cases. First off there are different colors some lighter than others the only ones that are the darkest red are the Viva cases and these seem to be more solid, but the draw back to these are the push out button’s they don’t work very good. And you sometimes have to pry out your disk it’s a bad design imo. And there are square back cases and round backs which are the norm, the hard ones to find are the square back and Universal cases with the fold away tab.
There are also different types of bindings square & rounded the Viva cases are rounded and don’t completely conform to the case mold in other words it doesn’t seal real good and leaves a small gap, but these seem to be the most solid. Here is a list of likes and dislikes about different cases. Also any cases that has the PP and triangle are manufactured to industry standards.
Nexus Amaray cases:
Rounded binding good seal.
Fold away locking tab good for taking on the road.
The pop out buttons don’t work very well.
Good window lamination for the cover art.
Opens and closes with good snap but not as easy as the square backs.
Rounded binding but more squared doesn’t conform to the case molding not a very good seal.
Terrible pop out button out of all the cases I dislike the Viva ones the most.
Darkest cases out there afaik.
Good window lamination for cover art.
Opens and closes with the same result as the Nexus.
Square back cases:
I don’t know who makes these ones but it is conformant to the industry standard PP same color as the Universal cases.
Square binding conforms to the case perfect with a good seal.
The best pop out button to date always works and feels solid when putting back the disk as it has a three claw lock.
Easy archiving because there is no fold away tabs to deal with and always feel more secure when closing the cases compared to Universal cases.
Mermax cases are the cheapest with no logo, does not seal very well but does have a good pop out button as good as the square backs. Very light in color and there is no PP so it does not conform to the indusry standard.
So I decided to use all of the square back ones for my library because it’s easier to read the titles due to it being more squared and not rounded. And it also gives me that bookish feeling when browsing and opening up the cases.
The Universal ones are strictly for traveling because of the locking tab. I’ve already did all of my HD DVD’s with the square backs and I am about to do all of my Blu ray movies in the same cases I like the red over blue and since it’s a dual player why keep two colors anyway.
