This is why 1080p is so much better than either 720p or 1080i, and why Blu-Ray at 1080p is capable of much higher quality than HD-DVD at 720p/1080i ...

So are you saying each individual 540 line field (two fields per frame) of the interlaced pair is exactly the same and just offset vertically by one pixel? Thus the 1080i actually has only 540 unique lines of information with them being effectively upper and lower half refreshed on an alternating 30 Hz basis?

I don't remember this being in the spec. I'm trying to find my copy, but I've misplaced it. ... Guess I'll have to download it and print it off again then read through it.
