it's somewhat difficult, and you usually lose most or all videos and movies, sometimes even entire game modes (i.e. burnout has the 2 player mode removed).
it's usually nothing you can do with 2 mouseclicks, it takes alot of hacking and messing around.
there are rip kits that will do that automatically, but that only works for certain versions and there are by far no kits for every game.
