Hey, Bruno...

I know that at first I said that it was related to the interlacing, but the more I look at that picture, the more I wonder if it's just deinterlacing artifacts. I mean, I know what a poorly deinterlaced image looks like, and that picture he posted looks significantly worse than that. It's almost like one of the two fields is damaged somehow. That's why a ground loop was listed in one of my suggestions... if there was 60-cycle ground loop noise being introduced on the input wire, couldn't it theoretically cause interference on only one of the two fields?

I mean, I can't imagine that all the fine ATI products cause an interlaced image to look that bad...
