I will have to try this again because it's a little difficult to visually process with the picture rolling. My impression was that the moire ripple pattern and location did not change, but as the picture content moves past it becomes more or less predominant. I suppose that effect could also happen because I had the DVD content paused(stationary picture) rather than random content change. Sort of gives the appearance of magnetic interference pattern. I wish I could photograph it better but my camera messes with it and often shows more of a moired rainbow pattern.

Edit: or are you saying the ripples change but just stay prominent in the same area? That's what would be expected if it's caused by the interaction of the scan lines and the phosphor pattern. If this is the case, it shows it's not a signal problem because it is modified by the exact position of the scan lines.
