The "shudder" you are describing definately sounds like an issue from your source signal and not your Pioneer set. The only thing I currently have hooked up to my set is an Oppo970 DVD player, which I am using for breakin, and I see no issues of shuddering. As for the jagged lines, what type of feed are you giving your set? Are you having the DCT-6416 process it to 720p and then passing it to your Pioneer? If so, try just passing the sources native signal, unprocessed, to the Pioneer and let it do the deinterlacing. You could be getting a little noise due to processing the signal multiple times. Do you have a picture of what you are talking about for jagged lines, as I don't think I have seen those on my display yet.
