I’m pretty sure any “extra gore” is solely referring to the shot of Ed Flanders impaled on the antlers, though there are also alternate angles of one or two other scenes in the feature version if I remember correctly.

Here’s an excerpt from an Amazon customer review of the UK DVD:
“Regarding this two dvd set. . . It’s two discs, 184 minutes here so the uncut version. Picture is full frame. The sound is in mono and subtitles are English, Danish, Czech, Italian, Danish, Finnish, Norw, Polish, Spanish, Swedish and Portugese! As has been previously said, at the beggining of each disc there is a scene synopsis (spoilers!) so I would just select scene 3 on disc one and 29 on disc two until the proper movie starts or it may spoil it for you!”

So take that as verification that the UK DVD does indeed have the recaps at the beginning.
