Yep, and you'll notice that DVD videos are only consumer releases, since
although they're better than VHS (which is actually the worst form of video
storage, they are actually very high compression. the DVD video artifacts
are hard to notice, because MPEG-2 compresses using GOP (groups of
pictures), whereas I think DV is on a frame by frame basis, which is much
quicker, and thus is (was if you're right about the ompression) more
feasable for on the fly in camera use. Also, there is very heavy
compression on the audio of DVDs, I'm sure you've heard it, whereas there is
none on DV.

Well, the data size matches roughly, so that could be possible.

Absolutely certain. I edit with it, data space is always foremost on my
mind.

I'm inclined to say that DV is better than DVD, but i still haven't had a
chance to look at DVDs on TV, so i really can't. but once again, these
releases are for the /consumer/ market.
