Keep in mind that live HDTV -- like sports from ABC, ESPN, or Fox is broadcast at 720p60 which gives it a significant display refresh advantage over 24 fps film based source. But like Tommy says after watching a fair amount of HD DVD then you can get very sensitive to annoying MPEG2 (or just various bandwidth bottleneck) blocky artifacts caused by the video compression codec. The only time that I have seen any artifacts with HD DVD titles is just on a very few (<4) stop frame scenes. Cases where the video compressionist & QC may have missed. I can think of a MI3 scene when the refridgerator is being opened as a rare example. Very hard to see at normal playback speed unlike broadcast TV.

There still is normally a definate "look" difference between film versus video camera sources.
