i have the widescreen version and am playing on the Ps2 and do not seem to have the problem you guys are having with sound and chapter 26, (thank god). i will keep a eye out for anything if it comes up, also i do not think the box is not to bad as long as you take care of it and keep it stored on a good shelf it should last, mine does not seem like paper looks more like cardboard had looks like it should last. is there more than one type of box released for it?
edit, added more stuff
