Encoding Problem With Forgetting Sarah Marshall?

[riseagainst]

Playback is on Sony BDP-S300 w/ latest firmware update (v. 4.20). I picked up the blu-ray last night and about mid-way through the movie it jumped back to the beginning. In the scene immediately following when the two are in the ocean, whenever it hits a certain point it immediately goes back to the beginning. I played it back several times at this point and it continued going back to the start. I had to skip that scene in order to watch the movie. This occurred on both versions of the movie, although strangely on the alternate version it happens about 5 seconds later in the movie.

Is anybody else experiencing playback problems like this on Forgetting Sarah Marshall?
