the_lhc:
I have to admit I've been surprised by some of the jerkiness on slow panning shots with Blu-rays with my S760. It's feeding my KRP-500a with 1080/24p (according to the on-screen display), which the TV should be fine with but with, for example, 2001, the scenes where the Jupiter ship moves slowly across the screen have noticable judder (although these are the sort of scenes where it'll be most noticable).
I don't know whether I need to change anything on the TV, like the drive mode or something, I did switch it to a different mode to stop the jerkiness with football from SkyHD, although I actually switched it to the mode they recommend for movies, not sport, as that seemed to be better, I don't know whether that's one of the options that's specific to the input, rather than a general option, I didn't think it was but I guess I'll have to check.
Clare have you got any suggestions for the settings in the S760, I looked through them, turned most things off, where I knew what they were doing but some of them aren't entirely obvious as to their purpose.
Now if you'd said PS3.....THAT would have been blamed instantly
I cant remember what the options are on the Pioneer but ive had a similar problem on my sony. The solution was to change my FILM MODE to 1 (It directly affects movement depending on what framerate its given). 24fps was definitely smoother on that setting
