If so, look around for any motion smoothing setting to turn off.
I just purchased a 46" Samsung LED TV 6150, and have noticed that all of the television shows that we're watching have this "PBS" feel to them. I feel like I'm much more aware that they're being shot in studios, as if everything is just a bit more artificial. It's very hard to describe, but has anyone else noticed this effect?
I could be convinced that this is just an effect of the HD, but I had a different 46" tv before this one, and I didn't notice this.
