Someone please tell me I'm not crazy for thinking these are the same thing.

They're not the same thing.

More help then my friend. I'd like to get this down. AVF guys seem to think they are.

They both have the same timings and generally look electronically the same to the display device, but 1080i has twice the resolution.

1080i is essentially comprised of two 540 frames containing information about the same picture, from the same point in time, that gets laced together to provide a single picture. 540p contains full frames of information that are from different points in time and are displayed singly, all lines at the same time without needing to be laced back together.

In other words, you get 1080 lines of resolution or 540 lines of resolution. You might get twice as many "screen refreshes" with 540p, but it's still only 540 lines of resolution.
