There are no extra or extended scenes; too bad!
Once upon time...

Now, there are/were some geopolitics here..
In short:
The differences in length come from the fact that there are/were different (colour) television systems in the world and the frames-per-second rate varies --> some sort of
transfer is needed.
Film is (always) 24 frames per second (fps), the
European television/video/DVD system
PAL is 25 fps and the
North American television/video/DVD system
NTSC is 30 fps:

These television systems and technologies are decades old; see
here.
Film to PAL is done in a very simple way: the film is just 'speeded' up, i.e. the 1
st second of transfer: the 25
th frame in PAL is the 1
st frame of film's
2nd second. A better explanation
here. The sound is also 'pitched' up in film to PAL transfer unless taken care of somehow.
Film to NTSC is done in a more complex way called 2:3 pulldown: see
here. The frame structure is compromised but the length is retained. This pulldown causes some judder visible during slow, steady camera movements, especially horizontal panning.
So, both ways of transfer have their pros and cons but we are used to the cons and our eyes/ears don't see/hear anything 'different' after a while. Movies on television, VHS and DVD have always been like this.
[Also notice that every frame is divided into two fields in PAL and NTSC...]So, movies on PAL DVD's are 4 % shorter than on film or NTSC DVD's. BBM is some 129 min on PAL and some 134 min on film and NTSC.
[There is/was also SECAM; the French and the Russians needed to have something of their own...
]The world is finally getting rid of some old politics:
Blu-ray is 24 fps
everywhere (unless
intentionally wanted otherwise...).
[The engineer goes now to sauna...
