Ripping PS2 Movie Files

[Cyber Akuma]

Does anyone have any tools or information about ripping the movies from a PS2 game? I dont care about PSS format movies, I know hwo to rip those but only like 10% of PS2 games use that format. Most games use their own format or put all the movies into one file, like a movies.dat (metal gear solid 2), movies.pak (guilty gear XX) split the entire game into many identical files (Chobits), or they dont even show your the files on the dvd (Final Fantasy X, Kingdom Hearts). Does anyone know of any way to rip these kinds and other kinds of movies? I know its possible because I have seen these movies ripped straight off the source files before (not with a capture card) but I googles for days and cant find any info on it.
