Uncompressed hd is 1.5 gb/sec.  DVDs and HD-DVDs and BluRay are all MPEG-2
video, which by definition is compressed video.

Actually, "by definition" is a bit strong.  I have never seen any mechanism
in the MPEG-2 specification and annexes that would permit transmission of
uncompressed audio or video.  I'm only making the assumption that "no
mechanism" means "only compressed audio and video."

The "cool kids" belief that broadcast HD is the quality benchmark and is
free, is correct. No need in overloading them with the "useless" facts! Of
course HD DVD and Blue Ray are something else......and they are also
compressed, I assume anyway.
