Harry Potter and the Deathly Hallows Part 2 frame skip/freeze

My BDP5100/05 seems to have the same problem as described here:

An apparently identical issue is also documented here

http://www.amazon.co.uk/review/R16722S7I36IC4/

-- seems to be an issue with other players too, but one that's been resolved with a firmware upgrade. I've upgraded to the latest firmware, which is version 1.57, 2011-07-29, but the issue still exists for me.

An example of the freeze is close to the beginning of Chapter 11, around 40:43
