Yes, the DRC reality/clarity settings do impact the appearance of artifact. The dot crawl I have been describing looks how wikipedia describes it and shows in their sample image - what I would call "animated checkerboard patterns" at color transitions . Unfortunately, I have been using the term "jaggies" incorrectly, so I apologize for that. I had been using it to mean the same thing as dot crawl, but have since realized the mistake. I was able to perform the A/B test in a local retail using their 50A2000 and Sony DVP-NC85H dvd player (same as mine). The results were identical to my set up at home. One of my animated dvds revealed the artifact immediatly with s-video, but was ok with composite. Another one of the 'tests' I tried you may be able to comfirm: At the very beginning of ep2 (and probably the other 5), a 20th Century Fox logo appears, then pulls back to reveal text to the right that reads "20th Century Fox Home Entertainment". When using an s-video cable, there is a small but noticeable amount of "animated checkerboard patterns" at areas around this logo and text. Switching to composite, however, it cleans up. This is not a great example because it is small, short in duration, and compared to the animated dvd test, might go undetected. Other dvd's I have show it here or there, near text or logos, moreso on animated material, whereas this lower budget dvd we have is like a torture test. The question is, of what?

That could be showing up on a A2000 as some sort of artifact in a color fringe. Does changing DRC settings change the effect?
