BBC Life Blu-ray WON'T play on US PS3

So I purchased BBC Life on Blu-ray here: http://www.amazon.com/gp/product/B002UXRGM0/ref=cm_cr_mts_prod_img


According to most reviews, this set should play fine on USDM PS3's. Well after the initial splash screens and video intro, it goes to a blank screen and refuses to even go to the Title menu! This is beyond frustrating. Is there such a thing as 1080p/50? Some people have said that my PS3 Slim , mfg in Sept. 2011, can't read this format. I checked and this release, although a UK release, is region free so that should NOT be a problem.


By the way, I'm running my PS3 through my Denon AVR 1910. Anyone know what might be going on?
