I see. This indeed sounds very dubious. A pity, because were the media
bigshots less zealous in their efforts, they would more easily extract
money from me, via the movie rental place down the street which offers
DVDs as well as VHS tapes.

OK. So I guess that means it must be compressed somehow, since I'm
getting about 77 gigs for an 800x600 pixel movie at 16bpp at 24 fps
(yes I am picking those values somewhat arbitrarily since I have no
idea what the resolution/color depth/fps of a typical dvd movie is).
Also I guess that means I won't be downloading DVDs any time soon..

I wonder how it would look on a good TV monitor.. anyone have
experience with this?

Aha. A hardware decoder sounds like a convenient way to deal with the
proprietary encoding issue. Though possibly politically
questionable. Also financially.. I'm a student, so I was
hoping to save money via DVD vs. TV+VCR (also I just blew a lot of cash on
a nice monitor, and two CRTs in one apartment strikes me as a waste --
already one is too much IMHO, though lcd screens still too expensive..)
