Problem with Poltergeist Digibook BDisc ???

[demiscy]

I sat down to watch the movie when I realized there is a scene cut in the middle..

it's on the 00:34:13-14 mark. Where the father examines the chair, then it suddenly goes forward to the couple being outside of a neighboor's/friend's door with him opening and greeting them..

is this normal ?? I watch the movie the a 60GB PS3.
The disc doesnt skip though... the minutes/seconds go on as they should...
