the brief sequence I was talking about in the other thread. It looks like this was simply upscaled from SD, doesn't it? It's even more jarring in motion, actually.
Definitely not upscaled - there's so much more detail in the shot compared to the SD version. But there are certainly some issues with that particular shot, perhaps one of the resident videophiles here can shed some light on it.
This is an interlacing issue, the fields (odd lines / even lines) were switched. But then I would assume the blu-ray wouldn't contain interlaced video but rather progressive, so for some reason this interlaced piece of video was used which would also produce a result like this if your output was going to be progressive.
