<<Although DVD is digital, it is still just a digital version of NTSC (or
PAL) and as such is interlaced.>>


I haven't contributed to this list yet, as I know very little as yet about
stereo imaging (though I'm learning), but the one thing I *do* know a lot
about is video-- and that's not *quite* correct. Some DVDs, taken from
masters in NTSC or PAL interlaced formats, are indeed encoded as interlaced
fields...

*BUT*, DVDs that are encoded from full-frame sources like, say, motion
pictures, are usually encoded on the DVD as progressive full frames. It's a
lot more space efficient on the disc (24 frames per second instead of 50 or
60 fields per second, depending), and the DVD player does the grunt work of
converting the progressive frames into the proper interlaced format for the
viewer.

Sorry if that's a little off topic, but I wanted to clear that up. :)
