Is it me, or did they not de-interlace the video footage during the post production of the "Making Of" features?

I didn't check, but I suppose the source could be 1080i as opposed to 1080p, but sometimes, when there's motion and comps (graphics, lower thirds, etc) on screen at the same time, the comps look great, but the video looks interlaced.

I'm viewing with PowerDVD Ultra on a PC with a 1920x1200 monitor.
