Blu-rays with hidden languages and bi/multi-lingual menu implementation

[lgans316]

To see this in action, please set the BD menu language in your player to a language of your choice. If the desired language ain't available on the BD then the player will display the menu in default language (English). Examples of titles with such implementation are listed below.

Warner

Zodiac (Import)
Sweeney Todd (Import)
Harry Potter 1 ~ 5
Natural Born Killers
Dirty Harry
Ocean's Trilogy
Batman Begins
V for Vendetta
Gotham Knight
Perfect Storm
Once flew over the cuckoo's nest
Beetlejuice (??)
How the west was won
Interview with the vampire
Outbreak
Eraser
L.A Confidential (??)
Charlie and the Chocolate Factory
Gigi
An American in Paris
Pale Rider
The Matrix
Matrix Reloaded
Matrix Revolutions

BVHE

National Treasure 1 & 2
Enchanted
Shall we dance
Signs
Unbreakable

FOX

Day and Night Watch (JP / E.U / U.K Import)
Juno (NL Import)

I think most of the BVHE and Warner BD titles released in the past 6~8 months feature this hidden multi-lingual menu implementation.

One strange thing you will notice is the limiting of audio and subtitles. For example, the Japanese menu in Sweeney Todd (Import) doesn't list spoken languages/subs other than English & Japanese.
