Help in DVD System Parameters

[newjack]

Hello, I don'ts understand if these parameters are set by Player's hardware or they are only used to memorize dates by consumers.

that is if I insert the dvd on the player, the values in SPRM0, SPRM1, SPRM2 are modified automatically in according to the characteristics (Region) of the DVDPlayer or they indifferently have a default value that I find me in Japan or in Italy or in Australia ?

Thank you

SPRM 0 is set by the DVD player(you-configuration), and can't be changed. SPRM's 1&2 can be changed, and are when you change sub-title and/or audio stream if the DVD has multiple steams
