Pirates: At World's End resume issues

[scarpi]

Man I just rented this movie on blu-ray and it looks great and sounds fantastic. But it seems the "resume" function did not work properly on this disc. I'd press stop once and when I hit play, the player normally picks up where I left off. Well not with this disc, it kept going back to the beginning. It's the first disc I played on my new Sony player. Maybe it was just a screwed up rental disc? I was impressed with the picture and sound.
