a question about PBS "masterpiece" presentations of BBC material [with the usual apologies for duplication]

i chanced last night to watch the PBS "masterpiece mystery" presentation of an episode from the BBC's "foyle's war" series, and there were some aspects of the narrative structure of the program that seemed to me very peculiar . . . . it's possible that the beeb [with whose programs i'm largely unfamiliar] uses a different model of narrative organization than i'm used to -- but i suppose it's also possible that PBS re-edited the program [for audience and/or time considerations] and that some of the things i noticed were distortions of the original . . .

so . . . does anyone know whether PBS mucks around with beeb originals before presenting them, or whether they are presented in substantially original form?

thanks for any clues
