One HD movie takes up something like 20 GB. I wouldn't want to have

dishes or somesuch.
All you have to be able to do is to download the movie fast enough so
that you can play it while you are watching it.
Sure, but I'm saying that current internet speeds are not good enough
for that. If it's 20 GB for a 2 hour movie, that's 1 GB every 6
minutes, 167 MB every minute, or about 23 Mbps (megabits).
Maybe your point is that for a 2-hour movie, if it takes 5.5 hours to
download it, you really only have to wait 3.5 hours to start watching
it. I agree with that.
Well, more than that. It would only take a modicum improvement in
technology (either faster download, or more likely, better compression
methods) to push 5.5 hours down to 3.5 hours.
And to get two to one compression for movies must surely be easy. MP3
gets 10 to one, and personally I cannot hear any difference. I mean,
even if they only use half the pixels in the HD movies, who is going to
see the difference?
