    A couple nights ago, I spun up SW:AotC in the computer's DVD drive, and played it out to the projector. This, generally, looks better, because the computer does the de-interlace, the video scaling, AND the anamorphic extraction, rather than anamorphic compression that my projector does (thus giving me the most original information possible.)
    However, trying to be smart, I set the frame-rate of the display to 72Hz: three times the 24fps original source.
    In some of the pans in particular, there was a bit of an odd judder.
    Did I outsmart myself, and should I have picked either a 60 or 90Hz option, to keep to a multiple of the 30 frames that the player is de-interlacing from? I didn't have time to experiment with it, and I won't be able to get close to it for another three or four days, either... (sigh.. I'm working too many jobs right now.)

    actually, progressive films are saved on DVD at 24fps

    If it's a digital projector, most of them only display 60hz even though they accept other input rates.
