Why can you see more macroblocking in dark scenes, than in light scenes? I don't see much if any macroblocking anymore in Blu-rays but I definitely see it in 1080i TV shows.

Can you give us a visual example of what you mean?

It's generally down to the compression algorithms. They try to save bandwidth, so the detail just above black can look messy.

I wouldn't worry about it if your BDs look great, if they didn't it might be a calibration issue.
