Samsung 46c750looks like amatur camera when watching a movie?

Dear All,

i just got the 46c750. Untill now i owned a crt one of the last ones with HD... When i just got the first LCD the 46c750 a couple of days ago everything is perfect except one thing that makes it missrable when playing a movie it looks like a tv show or reality tv or a documentary it does not look like a movie going smooth and you know the kind of way the movies are shoot?

Can it be to much HZ or what is the problem?
I hope not all LCD are like this?
hopefully it can be fixed any help would be appriciated

Thanks,
