New BD drive, all movies are stuttering...

sounds like some kind of system resource issue. 6600 though should be more than enough to handle. how much system memory do you have? do you have other applications running, or a lot of stuff running in the background? Virus protection software can hog a lot of resources too. I'd first start with making sure only the default options are selected with your video card, then reboot your machine, shut down as many tray applications as you can, and try again. I have 6600, with 8800 nvidea graphics card 512mb. plus 4 gigs of ram, worked fine with 2gigs of ram too. anything less than 2 gigs you might run into issues.
