TVP5150AM1: TVP5150AM1 Video goes up

Hi,

I want to use TVP5150AM1 with a NTSC Camera. Now, The video goes up as you can see in the attached file:

I guess the problem might be with wrong height, But as I double check its size is 720*480 in driver.

I use two other PAL Cameras, It's ok, but sometimes for a few seconds at first, the video goes up like the NSTC one but then it becomes ok.

Question: What could be the problem with NTSC and how to solve it?

Thanks for your help
