That's not HD at all. Period. It would be obviously and totally
inferior to 1080x1920@24p, which is what HD-DVDs should be.

That last is false ... it CAN be easily seen, and noticed,
as it is actually AVAILABLE TODAY, almost every day. It
is visible on Fox OTA TV. It is clearly inferior to true HD 720p.

Craig (the >>), you really NEED to get true HDTV on a
respectable 720p or 1080p pixel-perfect 50 inch display
in your own home!
