Due to some comments about incompleteness of the "Studio support" section of my diatribe on BluRay, I spent some research time over on the BluRay official site, solicited feedback from a couple locations, and built a more accurate Studio Org Chart over at http://www.klipschcorner.com/. It does not include every single tiny little indy arm of every studio (like Fox Searchlight) but is farily complete. Who owns what rights to what is fairly complicated it seems.
