Query: Locks up my Blu-ray Player (BD P1400 - Samsung)

I own a regular DVD of these two movies and liked them so much that I thought of adding the blu-ray version to my collection. Unfortunately, the disc locks up the player when I tried to play The Chronicles of Riddick and could not go any further after I get to choose from the Theatrical Version Vs Directors Cut. I was able to play Pitch Black once thru the end while it locked up in between once. I could never get to play this movie again.
