Please help.....

Put a new Blu-ray drive into my Aurora, when I try to watch Avatar on Blu-ray there are big areas of pixelization. Like the frame rate is not in synch?

Software Playback:Cyberlink PowerDVD 10 

Blu-ray Drive Asus BW-12B1L : http://www.asus.com/Optical_Storage/Internal_Bluray_Drive/BW12B1LT/

Monitor Dell SP2309W : http://www.bit-tech.net/hardware/monitors/2010/01/23/dell-sp2309w-monitor-review/1

Graphics Card Dual 1792MB NVIDIA(R) GeForce(R) GTX 260 - SLI

I have watched Star Trek DVD which played back fine...

 

As I am new/noob what have I not realized when purchasing a Blu-ray drive. ....
