All you have to do is uninstall PowerDVD and purchase ArcSoft TotalMedia Theatre and that should enable smooth BluRay playback without any stuttering, slowdown, skipping and is compatible with high end video cards that should obviously be able run Blu Rays without a problem. You don't have to downgrade your drivers, use any 3rd party programs, or adjust your display settings below 60Hz. PowerDVD is cheaper than Arcsoft's player but you get what you pay for.

I personally lasted 2 months, yes 2 months on technical support on trying to resolve this issue with PowerDVD. They blamed my drivers, my display settings (Hz), and video card and finally gave up saying that they couldn't resolve the issue and ACTUALLY recommended me using ANOTHER player. So what is the point of purchasing PowerDVD? Well to rip yourself off, pretty much.

Throughout the 2 months of frustrating technical support they asked for my Dxdiag file more than 5 times! So Im assuming they use some kind of stall tactic to frustrate their customers hoping that they give up so they don't have to deal with the problem.

I also asked for a refund in relation to the failed technical support on their faulty overpriced product. The thing is i had to request a refund within 30 days but guess what.....the tech support issue lasted 2 MONTHS! Spare yourself the inconvenience and shop around before you invest in Cyberlink products.

PS I love how they have a monthly fee to get real-time phone support. So you make a low quality product, get customers to contact their lousy tech support (through messages) which will eventually have them buying their phone tech support membership.
