Have you set 24fps to on within the menu of your BR player?
If not please switch it on this will smooth out any judder but ONLY if you TV can accept a 24fps signal which i believe all the W series sony can.
Also the Tv should have a motionflow setting somewhere?
Can you check the model of your Tv as i am not aware of the W46000, but if it has the xbar type menu then it should have motionflow and like Kingfats says switch this to off for your bluray input.
Happy hunting in your menus but i am sure we can get you there eventually
