Yep! You are 100% right. I thought it was something I screwed up on my machine but since intalling version 7057 X64 No more Blue Ray playback. I was able to play it on earlier builds. Maybe,,,no, hopefully they will sort this out as it is a very integral part of my media center system.
Forgot to mention that I have and was able to use Cyberlink's Power DVD Bluray edition before upgrading to 7057 which has killed all BluRay playback at least on my machine.
