Is my picture right?

[ShiftY]

Hello,

I have a sony bravia and a ps3 hooked with a hdmi cable, when i play blu-ray movies some movies look good and some movies look "grainy / fuzzy" in places, im fairly new to HD and Blu-ray and i have a calibration disk coming in the main but is this ment to look like this?

Ive looks on this site for some movies i have

Independence Day
https://www.blu-ray.com/movies/scree...199&position=8

The Grainy / Fuzzy look on the white wall, this also is noticeable when looking at a sky in a movie.

Some movies look fine other dont look so good, is this due to the age of the movie and how good it is converted to blu? or is something wrong with my tv?

Thanks,

Shifty
