Technical question re blue ray technology

[BraveRobot]

Hi. My friend has a nice 52" LCD Sony and a Sony Blu ray player hooked together with an HDMI cable. I watched No Country For Old Men on it. This is the first time I've watched anything on blu ray so I had a couple questions I was hoping you experts could clear up for me.

First, I noticed that sometimes the movement on the screen seemed sped up. It was most noticeable when people would move their hands quickly. It was subtle at first but it was definitely there and it became annoying after a while. What was that?

The second thing I noticed was that watching a movie on such high resolution can sometimes make the movie look wrong. It's possible this is because his TV was calibrated wrong and I wish I could be more descriptive but it's really hard to put my finger on why it looked wrong. Maybe there was too much contrast and it looked fake. I'm not sure. Does anyone know what I'm talking about?

I don't know the models of either his TV or the blu ray player but I think he got them at Best Buy and they're both new. Thanks guys!
