Repasando el hilo creo que no se ha comentado el tema de la sangre que le falta al bluray.
Resulta que en el Director's Cut hay escenas en las que salen salpicaduras de sangre que no salen en la versión de cine. Pues en el DC del bluray no salen y en el DC del dvd sí (al menos en el alemán). Esto se debería al seamless branching del bluray. Puesto que algunas de esas escenas son en sí mismas idénticas (excepto por la sangre) para ambas versiones, en el bluray parece que usan las de la versión de cines, o sea, sin salpicaduras, para el seamless branching de ambos montajes.
Comparativa Theatrical Cut vs Director's CutThe following versions were checked:
US-DVD (Theatrical version and Director's Cut) missing blood splatters
German Blu-ray (Theatrical version and Director's Cut) missing blood splatters
English Blu-ray (Theatrical version and Director's Cut) missing blood splatters
German DVD (Director's Cut only) containing all blood splatters
The most plausible reason for the missing blood splatters is the use of seamless branching. In this technique, two different versions are not stored separately on a DVD or Blu-ray, but identical parts are stored once and the differing parts separately. When a variant scene comes up, the respective is chosen and then it jumps back to the identical main part. The viewer normally does not notice this jump.
Should seamless branching have been the reason, then the producers of the DVD or Blu-ray have either forgotten to build in the alternative image in the below-mentioned scenes or have ignored it willingly, since they considered it unimportant. It always involves only a few frames, which differ minimally. The runtime stays constantly the same.

The seamless branching versions miss blood at 10 parts of the film.
