Cyberlink PowerDVD 7 1.1 Profile

[dunjenkeepa]

I've had a Pioneer Blu Ray Rom drive on my computer since last year and purchased PowerDVD ultra shortly after. Not had any major issues until this week when I got 3:10 to Yuma and Resident Evil:Extinction Blu Rays from Amazon DVD rental. Like many others 3:10 to Yuma is back in the post unwatched as I couldn't get past the menu, even with the update that was supposed to fix the issue! Resident Evil played, but not perfectly - every now and again the frame rate dropped to a few frames a second, like a stuttering effect. I'm wondering does the new 1.1 blu ray profile require more PC processing power? Or is this stuttering issue likely related to PowerDVD ? I've got retail versions of Spiderman III and Harry Potter 5 which play perfectly and multiple DVD rentals from Amazon have not caused any stuttering issues ?
