PS2 Tech Question

[ASTG]

okay first i wanna go on record as sayign that this thread is not to be a discussion about piracy, this is simply a question about how a ps2 works, if any mods feel that this borders on something that sshould not be discussed on this board (and i do agree that it could be seen that way) then you can close it and remove my comment...

basically what i would like to ask is this,

i am currently lending my sister my own DVD player along with many of the DVDs in my collection (she is recovering from an operation and though i try to visit her often and she does live with her fiance, he has work and i have 2 jobs and uni, so we cant be with her 24/7, so loaning my dvd player is the least i can do,

i have been using my ps2 as a dvd player since then, recently i tried playing a few home movies i made and burned to dvd, it all worked perfectly,

so my question is, if a ps2 can play a burned dvd video, why can it not play a copied game without the use of a mod chip or a boot disc?

please lets stick to a tech talk of the ps2 and not go into a talk of pirated games.

cheers,
ben

It has to do with what is, or isn't, encoded on the disc.

A burnt home movie is the same (in essence) to a PS2 / DVD player as any other DVD.

A game disc has, for want of a better word, a boot sector that is put on the disc at time of manufacture, and can't be copied due to it's location or whatever (Is that non-specific enough?)

The console (be it PS1, PS2, XBox...) detects that the disc is a GAME disc, and looks for this information. Because it can't be copied due to the methods used, it simply doesn't exist on a copied disc, and the console goes no further.

A modified console (which is perfectly legal due to a previous court battle in Australia) can use a variety of methods to simply bypass this "disc test"
