Choppy or laggy Blu Ray

[Phalinx666]

Alright I began having this problem last night when my brother wanted to watch Hellboy on the computer. I have a Pioneer Blu Ray / DVD burner drive, GeForce 8800, 24" Acer LCD Screem, and the drive came with WinDVD8 player software. I have been able to watch all my Blu Rays on my computer and last movie I watched was Rambo which I had to change region settings in WinDVD8 to play. Since, I've updated my video card driver and well last night when he put in Hellboy it was laggin or choppy play back. It was so bad the menu took forever to load up with the constant choppy play. I also put in other Blu Rays which also had the same choppy play.

So I spent about a hour fooling around in the Nvidia settings along with the WinDVD8 settings but could not fix this problem. I'm not sure what the cause if this could be other than the last update to my video card since this problem began after I updated it. I noticed Nvidia has a new update so when I get home I'll try that but just wondering if anyone else has had a problem like this and what the cause may be. Thanks in advance for any information!
