Making random truly random

[Luxo]

The random number generator in DVD players is not reliable. On most software DVD players (and some set-top players), the random "seed" is hardcoded and players come up with the same random number sequence every time the player is turned on. This is why some people never see alternate menu themes in Star Wars Episodes 1+2, for example.

I'm wondering if there is a way to get the player to come up with a truly random number every time. Perhaps it is possbile to base a random number on user input, or time spent on a menu before pressing a button.

I'm using Maestro, but Scenarist insight is equally useful. Thanks.

yeah right, coz cheap players(especially made in china) doesn't have enough memory or maybe it has but not good. and also they don't play
dvds exact resolution. most dvds are 720X480 but when you watch iton tv,the right part is cut off but 16pixels(704X480)

You could use a GPRM in counter mode.

sort of on this topic, does anyone know how i can stop this random number generator from working- i'm trying to back up the both starwars eps 1 and 2 and the menus are taking up a significant amount of the disc (400mb+) now seeing as dvdrb doesn't reencode the menus, i'd rather say have the director's commentary than two of the three themed menus that get selected at random. I had blanked two of the menus using DVD-Remake, but now roughly a third of the time the menu i kept loads fine but the other two thirds, after the starwars screen the menu locks, i'm hoping this can be fixed with a simple editing of the ifo :confused:

Is there anyway at all (say ifo edit) that i can force the the random generator to just pick the first menu?

and if so should i be looking in video_ts.ifo or in the VTS_01.ifo (as the menus are in VTS_01.vob

any help would be much appreciated

Just use DvdReMake one step further and change R[X] = random Y command
to R[X] = Z (where Z corresponds to menu you've kept)

Oh my god, thanks, Dimad, sorry i didn't get your explanation on the other thread.

Man is ther anything your program can't do?
