NVidia Quadro Weird Lines Problem - Please Help!

[kfederer]

I have a HP XW8400 workstation that came with the NVidia Quadro FX1500 card. It is connected to a Dell 2407WP-HC dual display. While recording video directly from the screen, I notice that there are horizontal lines that move across the screen. I cannot see these lines in normal view. The monitor is set at the default 60hz and recording at NTSC 30 frames per sec should not be a problem using an LCD monitor.
The video recording works fine on my laptop LCD, as well on one other computer that I checked (low end, no graphics card). I also connected another monitor to my system and same result.
So it seems like the issue has something to do with the graphics card? Could it be that I got a faulty card? Or is there anything need to change with the setup?

Thanks for your help!

Here is exactly my problem: http://www.youtube.com/watch?v=TnApFzmd9NY In this video if you look at the ViewSonic monitor there are no lines in the recording, whereas the Dell does. Any help would be greatly appreciated. Thanks.
