What I have to do to play my dvd backups???

sorry, charly! My ps2 is pal and it has only 1 week. I have not tried that methods yet. Are you able to tell me if there is any way to play this backups in it without changing my modchip? Moreover, I think that the modchip that you are talking about is forbidden here in my country (spain). My modchip is an internal one.
