Is this proper quality?

Hi!

I recently bought myself a new computer with a nvidia 9800GX2 gfx that has DVI exits and a new monitor; Benq FP241W (is compatible with hdmi/dvi/vga).
The problem i'm having is that most movies are grainy, I've read around the forum and it appears that this is sometimes intentional, but I'm even noticing some (not much though) grain in animated movies.

I've put up a screen of casino royal 1080i that i consider being way to grainy, but maybe I'm overreacting and its an acceptable amount?

I'd appreciate any answers, not knowing whether something needs to be fixed or if I'm just being way to picky is driving me nuts!
