Surely, many here have seen "How it's Made" on the Discovery Channel.

Does anybody have a clear understanding how they cram in so much HD goodness in such little space. Most of these HDDVDs are the equal to their 35mm counterparts on multiple reels weighing in at 'heavyweight'.

Don't suppose that would make a good HIM program, do you?

IIRC, HIM is a Canadian production. As usual, Canadian productions tend to suck and/or being very late in the game.
