I just did a bit more reading on this... looks like some deinterlacers will blur the image to cover artifacts when running in "bob" mode (essentially de-interlacing a field at a time, displaying each line twice), and will fall back to "bob" mode unless they can recognize patterns in the incoming video. A DVD player can get cues from flags in the MPEG stream but I don't think those flags get passed through into the video.

I'm starting to wonder if it was such a good idea to get the higher end Sony CRT (with progressive scan and deinterlacing) for my parents if they are going to be mostly watching standard NTSC TV programs. I hadn't realized how many artifacts are generated when de-interlacing normal video...
