Let me give you an example:
How much space would a 1920 x 1280 lossless signal take up?
1920 x 1280 x 3 bytes/pixel (24-bit color) x 30 frames/second = about
220 MB/second. The best lossless compression I've seen can reduce
that by about 50%, so let's say 110 MB/second. That's 1 GB for nine
seconds, or 45 minutes for a 300GB disc.
As long as there's a better resolution out there, people will be
demanding it...
(Besides - ever watch "Futurama"? A 300GB disc may be just enough to
hold a Harold Zoid holographic short...)
